Instance Method Summary collapse

Instance Method Details

#searchable(options = {}, &block) ⇒ Object

Makes a class searchable if it is not already, or adds search configuration if it is. Note that the options passed in are only used the first time this method is called for a particular class; so, search should be defined before activating any mixins that extend search configuration.

The block passed into this method is evaluated by the Sunspot.setup method. See the Sunspot documentation for complete information on the functionality provided by that method.

Options (+options+)

:auto_index::

Automatically index models in Solr when they are saved.
Default: true

:auto_remove::

Automatically remove models from the Solr index when they are
destroyed. <b>Setting this option to +false+ is not recommended
</b>(see the README).

:ignore_attribute_changes_of::

Define attributes, that should not trigger a reindex of that
object. Usual suspects are updated_at or counters.

:include::

Define default ActiveRecord includes, set this to allow ActiveRecord
to load required associations when indexing. See ActiveRecord's 
documentation on eager-loading for examples on how to set this
Default: []

Example

class Post < ActiveRecord::Base
searchable do
  text :title, :body
  string :sort_title do
    title.downcase.sub(/^(an?|the)/, '')
  end
  integer :blog_id
  time :updated_at
end
end
