=== Usage
|
||
|
|
|
||
|
|
Add the library to your Gemfile:
|
||
|
|
|
||
|
|
[source,ruby]
|
||
|
|
------------------------------------
|
||
|
|
gem 'elasticsearch-rails'
|
||
|
|
------------------------------------
|
||
|
|
|
||
|
|
Include the extension module in your model class:
|
||
|
|
|
||
|
|
[source,ruby]
|
||
|
|
------------------------------------
|
||
|
|
class Article < ActiveRecord::Base
|
||
|
|
include Elasticsearch::Model
|
||
|
|
end
|
||
|
|
------------------------------------
|
||
|
|
|
||
|
|
Import some data and perform a search:
|
||
|
|
|
||
|
|
[source,ruby]
|
||
|
|
------------------------------------
|
||
|
|
Article.import
|
||
|
|
|
||
|
|
response = Article.search 'fox dog'
|
||
|
|
response.took
|
||
|
|
# => 3
|
||
|
|
------------------------------------
|
||
|
|
|
||
|
|
It is possible to either return results as model instances, or decorated documents from Elasticsearch,
|
||
|
|
with the `records` and `results` methods, respectively:
|
||
|
|
|
||
|
|
[source,ruby]
|
||
|
|
------------------------------------
|
||
|
|
response.records.first
|
||
|
|
# Article Load (0.4ms) SELECT "articles".* FROM "articles" WHERE ...
|
||
|
|
=> #<Article id: 3, title: "Foo " ...>
|
||
|
|
|
||
|
|
response.results.first._score
|
||
|
|
# => 0.02250402
|
||
|
|
|
||
|
|
response.results.first._source.title
|
||
|
|
# => "Quick brown fox"
|
||
|
|
