CircleCI build

A first-party Ruby client for building excellent, relevant search experiences with Elastic App Search.

Contents


Getting started 🐣

To install the gem, execute:

gem install elastic-app-search

Or place gem 'elastic-app-search', '~> 7.9.0' in your Gemfile and run bundle install.

Versioning

This client is versioned and released alongside App Search.

To guarantee compatibility, use the most recent version of this library within the major version of the corresponding App Search implementation.

For example, for App Search 7.3, use 7.3 of this library or above, but not 8.0.

If you are using the SaaS version available on swiftype.com of App Search, you should use the version 7.5.x of the client.

Usage

Setup: Configuring the client and authentication

Using this client assumes that you have already an instance of Elastic App Search up and running.

Once done, a client can be instantiated using the [API_KEY] and the [API_ENDPOINT] URL of your App Search setup:

require 'elastic-app-search'

client = Elastic::AppSearch::Client.new(:api_key => 'private-xxxxxxxxxxxxxxxxxxx', :api_endpoint => 'http://localhost:3002/api/as/v1/')

Note:

The [API_KEY] authenticates requests to the API. You can use any key type with the client, however each has a different scope. For more information on keys, check out the documentation.

Swiftype.com App Search users:

When using the SaaS version available on swiftype.com of App Search, you can configure the client using your [HOST_IDENTIFIER] instead of the [API_ENDPOINT]. The [HOST_IDENTIFIER] can be found within the Credentials menu.

require 'elastic-app-search'

client = Elastic::AppSearch::Client.new(:host_identifier => 'host-c5s2mj', :api_key => 'private-xxxxxxxxxxxxxxxxxxx')

API Methods

This client is a thin interface to the Elastic App Search Api. Additional details for requests and responses can be found in the documentation.

Running Tests

export AS_API_KEY="[API_KEY]"
export AS_ADMIN_KEY="[ADMIN_API_KEY]"
export AS_HOST_IDENTIFIER="[HOST_IDENTIFIER]"
bundle exec rspec

You can also run tests against a local environment by passing a AS_API_ENDPOINT environment variable

export AS_API_KEY="[API_KEY]"
export AS_ADMIN_KEY="[ADMIN_API_KEY]"
export AS_API_ENDPOINT="http://[HOST_IDENTIFIER].api.127.0.0.1.ip.es.io:3002/api/as/v1"
bundle exec rspec

Debugging API calls

If you need to debug an API call made by the client, there are a few things you could do:

  1. Setting AS_DEBUG environment variable to true would enable HTTP-level debugging and you would see all requests generated by the client on your console.

  2. You could use our API logs feature in App Search console to see your requests and responses live.

  3. In your debug logs you could find a X-Request-Id header value. That could be used when talking to Elastic Customer Support to help us quickly find your API request and help you troubleshoot your issues.
