$ bundle

class Post

end

Post.es.search 'test text' # shortcut for Post.es.search({q: 'test text'})
result = Post.es.search body: {query: {...}, facets: {...}} etc
result.raw_response
result.results # by default returns an Enumerable with Post instances exactly
               # like they were loaded from MongoDB
Post.es.index.create(Post.es.index_all) # create index (done automatically on app boot)
Post.es.index.destroy(Post.es.index.delete) # drop index
Post.es.index.reset # recreate index
Post.es.index.refresh # force index update (useful for specs)
Post.es.client # Elasticsearch::Client instance

response = Mongoid::Elasticsearch.search 'test'

Reindexing

All models

rake es:reindex will reindex all indices managed by Mongoid::Elasticsearch

One model - Simple bulk

This is the preferred (fastest) method to reindex everything

Music::Video.es.index_all

One model - Simple

Communities::Thread.es.index.reset
Communities::Thread.enabled.each do |ingr|
  ingr.es_update
end
