Searchkick

:rocket: Intelligent search made easy

Searchkick learns what your users are looking for. As more people search, it gets smarter and the results get better. It’s friendly for developers - and magical for your users.

Searchkick handles:

  • stemming - tomatoes matches tomato
  • special characters - jalapeno matches jalapeño
  • extra whitespace - dishwasher matches dish washer
  • misspellings - zuchini matches zucchini
  • custom synonyms - qtip matches cotton swab

Plus:

  • query like SQL - no need to learn a new query language
  • reindex without downtime
  • easily personalize results for each user
  • autocomplete
  • “Did you mean” suggestions
  • works with ActiveRecord, Mongoid, and NoBrainer

Searchkick 1.0 was just released! See instructions for upgrading

:tangerine: Battle-tested at Instacart

Build Status

Get Started

Install Elasticsearch. For Homebrew, use:

brew install elasticsearch

# start the server
elasticsearch

Add this line to your application’s Gemfile:

gem 'searchkick'

For Elasticsearch 2.0, use the version 1.0 and above. For Elasticsearch 0.90, use version 0.6.3 and this readme.

Add searchkick to models you want to search.

class Product < ActiveRecord::Base
  searchkick
end

Add data to the search index.

Product.reindex

And to query, use:

products = Product.search "apples"
products.each do |product|
  puts product.name
end

Searchkick supports the complete Elasticsearch Search API. As your search becomes more advanced, we recommend you use the Elasticsearch DSL for maximum flexibility.

Queries

Query like SQL

Product.search "apples", where: {in_stock: true}, limit: 10, offset: 50

Search specific fields

fields: [:name, :brand]

Where

where: {
  expires_at: {gt: Time.now}, # lt, gte, lte also available
  orders_count: 1..10,        # equivalent to {gte: 1, lte: 10}
  aisle_id: [25, 30],         # in
  store_id: {not: 2},         # not
  aisle_id: {not: [25, 30]},  # not in
  user_ids: {all: [1, 3]},    # all elements in array
  category: /frozen .+/,      # regexp
  or: [
    [{in_stock: true}, {backordered: true}]
  ]
}

Order

order: {_score: :desc} # most relevant first - default

All of these sort options are supported

Limit / offset

limit: 20, offset: 40

Results

Searches return a Searchkick::Results object. This responds like an array to most methods.

results = Product.search("milk")
results.size
results.any?
results.each { |result| ... }

Get total results

results.total_count

Get the time the search took (in milliseconds)

results.took

Get the full response from Elasticsearch

results.response

Boosting

Boost important fields

fields: ["title^10", "description"]

Boost by the value of a field (field must be numeric)

boost_by: [:orders_count] # give popular documents a little boost
boost_by: {orders_count: {factor: 10}} # default factor is 1

Boost matching documents

boost_where: {user_id: 1}
boost_where: {user_id: {value: 1, factor: 100}} # default factor is 1000
boost_where: {user_id: [{value: 1, factor: 100}, {value: 2, factor: 200}]}

Conversions are also a great way to boost.

Get Everything

Use a * for the query.

Product.search "*"

Pagination

Plays nicely with kaminari and will_paginate.

# controller
@products = Product.search "milk", page: params[:page], per_page: 20

View with kaminari

<%= paginate @products %>

View with will_paginate

<%= will_paginate @products %>

Partial Matches

By default, results must match all words in the query.

Product.search "fresh honey" # fresh AND honey

To change this, use:

Product.search "fresh honey", operator: "or" # fresh OR honey

By default, results must match the entire word - back will not match backpack. You can change this behavior with:

class Product < ActiveRecord::Base
  searchkick word_start: [:name]
end

And to search (after you reindex):

Product.search "back", fields: [:name], match: :word_start

Available options are:

:word # default
:word_start
:word_middle
:word_end
:text_start
:text_middle
:text_end

Exact Matches

User.search params[:q], fields: [{email: :exact}, :name]

Language

Searchkick defaults to English for stemming. To change this, use:

class Product < ActiveRecord::Base
  searchkick language: "german"
end

See the list of stemmers

Synonyms

class Product < ActiveRecord::Base
  searchkick synonyms: [["scallion", "green onion"], ["qtip", "cotton swab"]]
  # or
  # searchkick synonyms: -> { CSV.read("/some/path/synonyms.csv") }
end

Call Product.reindex after changing synonyms.

WordNet

Prepopulate English synonyms with the WordNet database.

Download WordNet 3.0 to each Elasticsearch server and move wn_s.pl to the /var/lib directory.

cd /tmp
curl -o wordnet.tar.gz http://wordnetcode.princeton.edu/3.0/WNprolog-3.0.tar.gz
tar -zxvf wordnet.tar.gz
mv prolog/wn_s.pl /var/lib

Tell each model to use it:

class Product < ActiveRecord::Base
  searchkick wordnet: true
end

Misspellings

By default, Searchkick handles misspelled queries by returning results with an edit distance of one.

You can change this with:

Product.search "zucini", misspellings: {edit_distance: 2} # zucchini

To improve performance for correctly spelled queries (which should be a majority for most applications), Searchkick can first perform a search without misspellings, and if there are too few results, perform another with them.

Product.search "zuchini", misspellings: {below: 5}

If there are fewer than 5 results, a 2nd search is performed with misspellings enabled. The result of this query is returned.

Turn off misspellings with:

Product.search "zuchini", misspellings: false # no zucchini

Emoji

Search :ice_cream::cake: and get ice cream cake!

Add this line to your application’s Gemfile:

gem 'gemoji-parser'

And use:

Product.search "[emoji go here]", emoji: true

Indexing

Control what data is indexed with the search_data method. Call Product.reindex after changing this method.

class Product < ActiveRecord::Base
  belongs_to :department

  def search_data
    {
      name: name,
      department_name: department.name,
      on_sale: sale_price.present?
    }
  end
end

Searchkick uses find_in_batches to import documents. To eager load associations, use the search_import scope.

class Product < ActiveRecord::Base
  scope :search_import, -> { includes(:department) }
end

By default, all records are indexed. To control which records are indexed, use the should_index? method.

class Product < ActiveRecord::Base
  def should_index?
    active # only index active records
  end
end

To Reindex, or Not to Reindex

Reindex

  • when you install or upgrade searchkick
  • change the search_data method
  • change the searchkick method

No need to reindex

  • App starts

Stay Synced

There are three strategies for keeping the index synced with your database.

  1. Immediate (default)

Anytime a record is inserted, updated, or deleted

  1. Asynchronous

Use background jobs for better performance

  class Product < ActiveRecord::Base
    searchkick callbacks: :async
  end

And install Active Job for Rails 4.1 and below. Jobs are added to a queue named searchkick.

  1. Manual

Turn off automatic syncing

  class Product < ActiveRecord::Base
    searchkick callbacks: false
  end

You can also do bulk updates.

Searchkick.callbacks(:bulk) do
  User.find_each(&:update_fields)
end

Or temporarily skip updates.

Searchkick.callbacks(false) do
  User.find_each(&:update_fields)
end

Associations

Data is not automatically synced when an association is updated. If this is desired, add a callback to reindex:

class Image < ActiveRecord::Base
  belongs_to :product

  after_commit :reindex_product

  def reindex_product
    product.reindex # or reindex_async
  end
end

Analytics

We highly recommend tracking searches and conversions.

Searchjoy makes it easy.

Product.search "apple", track: {user_id: current_user.id}

See the docs for how to install and use.

Keep Getting Better

Searchkick can use conversion data to learn what users are looking for. If a user searches for “ice cream” and adds Ben & Jerry’s Chunky Monkey to the cart (our conversion metric at Instacart), that item gets a little more weight for similar searches.

The first step is to define your conversion metric and start tracking conversions. The database works well for low volume, but feel free to use Redis or another datastore.

You do not need to clean up the search queries. Searchkick automatically treats apple and APPLES the same.

Next, add conversions to the index.

class Product < ActiveRecord::Base
  has_many :searches, class_name: "Searchjoy::Search"

  searchkick conversions: "conversions" # name of field

  def search_data
    {
      name: name,
      conversions: searches.group(:query).uniq.count(:user_id)
      # {"ice cream" => 234, "chocolate" => 67, "cream" => 2}
    }
  end
end

Reindex and set up a cron job to add new conversions daily.

rake searchkick:reindex CLASS=Product

Personalized Results

Order results differently for each user. For example, show a user’s previously purchased products before other results.

class Product < ActiveRecord::Base
  def search_data
    {
      name: name,
      orderer_ids: orders.pluck(:user_id) # boost this product for these users
    }
  end
end

Reindex and search with:

Product.search "milk", boost_where: {orderer_ids: current_user.id}

Instant Search / Autocomplete

Autocomplete predicts what a user will type, making the search experience faster and easier.

Autocomplete

Note: If you only have a few thousand records, don’t use Searchkick for autocomplete. It’s much faster to load all records into JavaScript and autocomplete there (eliminates network requests).

First, specify which fields use this feature. This is necessary since autocomplete can increase the index size significantly, but don’t worry - this gives you blazing faster queries.

class Book < ActiveRecord::Base
  searchkick match: :word_start, searchable: [:title, :author]
end

Reindex and search with:

Book.search "tipping poi"

Typically, you want to use a JavaScript library like typeahead.js or jQuery UI.

Here’s how to make it work with Rails

First, add a route and controller action.

# app/controllers/books_controller.rb
class BooksController < ApplicationController
  def autocomplete
    render json: Book.search(params[:query], {
      fields: ["title^5", "author"],
      limit: 10,
      load: false,
      misspellings: {below: 5}
    }).map(&:title)
  end
end

Then add the search box and JavaScript code to a view.

<input type="text" id="query" name="query" />

<script src="jquery.js"></script>
<script src="typeahead.js"></script>
<script>
  $("#query").typeahead({
    name: "book",
    remote: "/books/autocomplete?query=%QUERY"
  });
</script>

Suggestions

Suggest

class Product < ActiveRecord::Base
  searchkick suggest: [:name] # fields to generate suggestions
end

Reindex and search with:

products = Product.search "peantu butta", suggest: true
products.suggestions # ["peanut butter"]

Aggregations

Aggregations provide aggregated search data.

Aggregations

products = Product.search "chuck taylor", aggs: [:product_type, :gender, :brand]
products.aggs

By default, where conditions apply to aggregations.

Product.search "wingtips", where: {color: "brandy"}, aggs: [:size]
# aggregations for brandy wingtips are returned

Change this with:

Product.search "wingtips", where: {color: "brandy"}, aggs: [:size], smart_aggs: false
# aggregations for all wingtips are returned

Set where conditions for each aggregation separately with:

Product.search "wingtips", aggs: {size: {where: {color: "brandy"}}}

Limit

Product.search "apples", aggs: {store_id: {limit: 10}}

Order

Product.search "wingtips", aggs: {color: {order: {"_term" => "asc"}}} # alphabetically

All of these options are supported

Ranges

price_ranges = [{to: 20}, {from: 20, to: 50}, {from: 50}]
Product.search "*", aggs: {price: {ranges: price_ranges}}

Moving From Facets

  1. Replace facets with aggs in searches. Note: Stats facets are not supported at this time.
  products = Product.search "chuck taylor", facets: [:brand]
  # to
  products = Product.search "chuck taylor", aggs: [:brand]
  1. Replace the facets method with aggs for results.
  products.facets
  # to
  products.aggs

The keys in results differ slightly. Instead of:

  {
    "_type":"terms",
    "missing":0,
    "total":45,
    "other":34,
    "terms":[
      {"term":14.0,"count":11}
    ]
  }

You get:

  {
    "doc_count":45,
    "doc_count_error_upper_bound":0,
    "sum_other_doc_count":34,
    "buckets":[
      {"key":14.0,"doc_count":11}
    ]
  }

Update your application to handle this.

  1. By default, where conditions apply to aggregations. This is equivalent to smart_facets: true. If you have smart_facets: true, you can remove it. If this is not desired, set smart_aggs: false.

  2. If you have any range facets with dates, change the key from ranges to date_ranges.

  facets: {date_field: {ranges: date_ranges}}
  # to
  aggs: {date_field: {date_ranges: date_ranges}}

Facets [deprecated]

Facets have been deprecated in favor of aggregations as of Searchkick 1.0. See how to upgrade.

products = Product.search "chuck taylor", facets: [:product_type, :gender, :brand]
p products.facets

By default, where conditions are not applied to facets (for backward compatibility).

Product.search "wingtips", where: {color: "brandy"}, facets: [:size]
# facets *not* filtered by color :(

Change this with:

Product.search "wingtips", where: {color: "brandy"}, facets: [:size], smart_facets: true

or set where conditions for each facet separately:

Product.search "wingtips", facets: {size: {where: {color: "brandy"}}}

Limit

Product.search "apples", facets: {store_id: {limit: 10}}

Ranges

price_ranges = [{to: 20}, {from: 20, to: 50}, {from: 50}]
Product.search "*", facets: {price: {ranges: price_ranges}}

Use the stats option to get to max, min, mean, and total scores for each facet

Product.search "*", facets: {store_id: {stats: true}}

Highlight

Specify which fields to index with highlighting.

class Product < ActiveRecord::Base
  searchkick highlight: [:name]
end

Highlight the search query in the results.

bands = Band.search "cinema", fields: [:name], highlight: true

Note: The fields option is required, unless highlight options are given - see below.

View the highlighted fields with:

bands.with_details.each do |band, details|
  puts details[:highlight][:name] # "Two Door <em>Cinema</em> Club"
end

To change the tag, use:

Band.search "cinema", fields: [:name], highlight: {tag: "<strong>"}

To highlight and search different fields, use:

Band.search "cinema", fields: [:name], highlight: {fields: [:description]}

Additional options, including fragment size, can be specified for each field:

Band.search "cinema", fields: [:name], highlight: {fields: {name: {fragment_size: 200}}}

You can find available highlight options in the Elasticsearch reference.

Similar Items

Find similar items.

product = Product.first
product.similar(fields: ["name"], where: {size: "12 oz"})

Geospatial Searches

class City < ActiveRecord::Base
  searchkick locations: ["location"]

  def search_data
    attributes.merge location: {lat: latitude, lon: longitude}
  end
end

Reindex and search with:

City.search "san", where: {location: {near: {lat: 37, lon: -114}, within: "100mi"}} # or 160km

Bounded by a box

City.search "san", where: {location: {top_left: {lat: 38, lon: -123}, bottom_right: {lat: 37, lon: -122}}}

Boost By Distance

Boost results by distance - closer results are boosted more

City.search "san", boost_by_distance: {field: :location, origin: {lat: 37, lon: -122}}

Also supports additional options

City.search "san", boost_by_distance: {field: :location, origin: {lat: 37, lon: -122}, function: :linear, scale: "30mi", decay: 0.5}

Routing

Searchkick supports Elasticsearch’s routing feature.

class Business < ActiveRecord::Base
  searchkick routing: true

  def searchkick_routing
    city_id
  end
end

Reindex and search with:

Business.search "ice cream", routing: params[:city_id]

Inheritance

Searchkick supports single table inheritance.

class Dog < Animal
end

The parent and child model can both reindex.

Animal.reindex
Dog.reindex # equivalent

And to search, use:

Animal.search "*"                   # all animals
Dog.search "*"                      # just dogs
Animal.search "*", type: [Dog, Cat] # just cats and dogs

Note: The suggest option retrieves suggestions from the parent at the moment.

Dog.search "airbudd", suggest: true # suggestions for all animals

Debugging Queries

See how Elasticsearch scores your queries with:

Product.search("soap", explain: true).response

See how Elasticsearch tokenizes your queries with:

Product.searchkick_index.tokens("Dish Washer Soap", analyzer: "default_index")
# ["dish", "dishwash", "washer", "washersoap", "soap"]

Product.searchkick_index.tokens("dishwasher soap", analyzer: "searchkick_search")
# ["dishwashersoap"] - no match

Product.searchkick_index.tokens("dishwasher soap", analyzer: "searchkick_search2")
# ["dishwash", "soap"] - match!!

Partial matches

Product.searchkick_index.tokens("San Diego", analyzer: "searchkick_word_start_index")
# ["s", "sa", "san", "d", "di", "die", "dieg", "diego"]

Product.searchkick_index.tokens("dieg", analyzer: "searchkick_word_search")
# ["dieg"] - match!!

See the complete list of analyzers.

Deployment

Searchkick uses ENV["ELASTICSEARCH_URL"] for the Elasticsearch server. This defaults to http://localhost:9200.

Heroku

Choose an add-on: SearchBox, Bonsai, or Found.

# SearchBox
heroku addons:add searchbox:starter
heroku config:add ELASTICSEARCH_URL=`heroku config:get SEARCHBOX_URL`

# Bonsai
heroku addons:add bonsai
heroku config:add ELASTICSEARCH_URL=`heroku config:get BONSAI_URL`

# Found
heroku addons:add foundelasticsearch
heroku config:add ELASTICSEARCH_URL=`heroku config:get FOUNDELASTICSEARCH_URL`

Then deploy and reindex:

heroku run rake searchkick:reindex CLASS=Product

Amazon Elasticsearch Service

Include elasticsearch 1.0.15 or greater in your Gemfile.

gem "elasticsearch", ">= 1.0.15"

Create an initializer config/initializers/elasticsearch.rb with:

ENV["ELASTICSEARCH_URL"] = "https://es-domain-1234.us-east-1.es.amazonaws.com"

To use signed request, include in your Gemfile:

gem 'faraday_middleware-aws-signers-v4'

and add to your initializer:

require "faraday_middleware/aws_signers_v4"
Searchkick.client =
  Elasticsearch::Client.new(
    url: ENV["ELASTICSEARCH_URL"],
    transport_options: {request: {timeout: 10}}
  ) do |f|
    f.request :aws_signers_v4, {
      credentials: Aws::Credentials.new(ENV["AWS_ACCESS_KEY_ID"], ENV["AWS_SECRET_ACCESS_KEY"]),
      service_name: "es",
      region: "us-east-1"
    }
  end

Then deploy and reindex:

rake searchkick:reindex CLASS=Product

Other

Create an initializer config/initializers/elasticsearch.rb with:

ENV["ELASTICSEARCH_URL"] = "http://username:password@api.searchbox.io"

Then deploy and reindex:

rake searchkick:reindex CLASS=Product

Performance

For the best performance, add Typhoeus to your Gemfile.

gem 'typhoeus'

And create an initializer with:

require "typhoeus/adapters/faraday"
Ethon.logger = Logger.new("/dev/null")

Note: Typhoeus is not available for Windows.

Automatic Failover

Create an initializer config/initializers/elasticsearch.rb with multiple hosts:

Searchkick.client = Elasticsearch::Client.new(hosts: ["localhost:9200", "localhost:9201"], retry_on_failure: true)

See elasticsearch-transport for a complete list of options.

Lograge

Add the following to config/environments/production.rb:

config.lograge.custom_options = lambda do |event|
  options = {}
  options[:search] = event.payload[:searchkick_runtime] if event.payload[:searchkick_runtime].to_f > 0
  options
end

See Production Rails for other good practices.

Advanced

Prefer to use the Elasticsearch DSL but still want awesome features like zero-downtime reindexing?

Advanced Mapping

Create a custom mapping:

class Product < ActiveRecord::Base
  searchkick mappings: {
    product: {
      properties: {
        name: {type: "string", analyzer: "keyword"}
      }
    }
  }
end

To keep the mappings and settings generated by Searchkick, use:

class Product < ActiveRecord::Base
  searchkick merge_mappings: true, mappings: {...}
end

Advanced Search

And use the body option to search:

products = Product.search body: {match: {name: "milk"}}

Note: This replaces the entire body, so other options are ignored.

View the response with:

products.response

To modify the query generated by Searchkick, use:

products =
  Product.search "apples" do |body|
    body[:query] = {match_all: {}}
  end

Multi Search

To batch search requests for performance, use:

fresh_products = Product.search("fresh", execute: false)
frozen_products = Product.search("frozen", execute: false)
Searchkick.multi_search([fresh_products, frozen_products])

Then use fresh_products and frozen_products as typical results.

Note: Errors are not raised as with single requests. Use the error method on each query to check for errors. Also, the below option for misspellings is ignored.

Reference

Reindex one record

product = Product.find 10
product.reindex
# or to reindex in the background
product.reindex_async

Reindex more than one record without recreating the index

# do this ...
some_company.products.each { |p| p.reindex }
# or this ...
Product.searchkick_index.import(some_company.products)
# don't do the following as it will recreate the index with some_company's products only
some_company.products.reindex

Reindex large set of records in batches

Product.where("id > 100000").find_in_batches do |batch|
  Product.searchkick_index.import(batch)
end

Remove old indices

Product.clean_indices

Use custom settings

class Product < ActiveRecord::Base
  searchkick settings: {number_of_shards: 3}
end

Use a different index name

class Product < ActiveRecord::Base
  searchkick index_name: "products_v2"
end

Use a dynamic index name

class Product < ActiveRecord::Base
  searchkick index_name: -> { "#{name.tableize}-#{I18n.locale}" }
end

Prefix the index name

class Product < ActiveRecord::Base
  searchkick index_prefix: "datakick"
end

Change timeout

Searchkick.timeout = 15 # defaults to 10

Set a lower timeout for searches

Searchkick.search_timeout = 3

Change the search method name in config/initializers/searchkick.rb

Searchkick.search_method_name = :lookup

Eager load associations

Product.search "milk", include: [:brand, :stores]

Do not load models

Product.search "milk", load: false

Turn off special characters

class Product < ActiveRecord::Base
  # A will not match Ä
  searchkick special_characters: false
end

Use Okapi BM25 for ranking

class Product < ActiveRecord::Base
  searchkick similarity: "BM25"
end

Change import batch size

class Product < ActiveRecord::Base
  searchkick batch_size: 200 # defaults to 1000
end

Create index without importing

Product.reindex(import: false)

Lazy searching

products = Product.search("carrots", execute: false)
products.each { ... } # search not executed until here

Make fields unsearchable but include in the source

class Product < ActiveRecord::Base
  searchkick unsearchable: [:color]
end

Reindex conditionally

Note: With ActiveRecord, use this feature with caution - transaction rollbacks can cause data inconsistencies

class Product < ActiveRecord::Base
  searchkick callbacks: false

  # add the callbacks manually
  after_save :reindex, if: proc{|model| model.name_changed? } # use your own condition
  after_destroy :reindex
end

Search multiple models

Searchkick.search "milk", index_name: [Product, Category]

Reindex all models - Rails only

rake searchkick:reindex:all

Turn on misspellings after a certain number of characters

Product.search "api", misspellings: {prefix_length: 2} # api, apt, no ahi

Note: With this option, if the query length is the same as prefix_length, misspellings are turned off

Product.search "ah", misspellings: {prefix_length: 2} # ah, no aha

Large Data Sets

For large data sets, check out Keeping Elasticsearch in Sync. Searchkick will make this easy in the future.

Testing

This section could use some love.

RSpec

describe Product do
  it "searches" do
    Product.reindex
    Product.searchkick_index.refresh # don't forget this
    # test goes here...
  end
end

Factory Girl

product = FactoryGirl.create(:product)
product.reindex # don't forget this
Product.searchkick_index.refresh # or this

Migrating from Tire

  1. Change search methods to tire.search and add index name in existing search calls
  Product.search "fruit"

should be replaced with

  Product.tire.search "fruit", index: "products"
  1. Replace tire mapping w/ searchkick method
  class Product < ActiveRecord::Base
    searchkick
  end
  1. Deploy and reindex
  rake searchkick:reindex CLASS=Product # or Product.reindex in the console
  1. Once it finishes, replace search calls w/ searchkick calls

Upgrading

View the changelog.

Important notes are listed below.

1.0.0

Breaking Changes

  • ActiveRecord 4.1+ and Mongoid 3+: Attempting to reindex with a scope now throws a Searchkick::DangerousOperation error to keep your from accidentally recreating your index with only a few records.
  Product.where(color: "brandy").reindex # error!

If this is what you intend to do, use:

  Product.where(color: "brandy").reindex(accept_danger: true)
  • Misspellings are enabled by default for partial matches. Use misspellings: false to disable.
  • Transpositions are enabled by default for misspellings. Use misspellings: {transpositions: false} to disable.

0.6.0 and 0.7.0

If running Searchkick 0.6.0 or 0.7.0 and Elasticsearch 0.90, we recommend upgrading to Searchkick 0.6.1 or 0.7.1 to fix an issue that causes downtime when reindexing.

0.3.0

Before 0.3.0, locations were indexed incorrectly. When upgrading, be sure to reindex immediately.

Elasticsearch Gotchas

Inconsistent Scores

Due to the distributed nature of Elasticsearch, you can get incorrect results when the number of documents in the index is low. You can read more about it here. To fix this, do:

class Product < ActiveRecord::Base
  searchkick settings: {number_of_shards: 1}
end
