def multi_search(options={}, &block)
  default_options = {:type => document_type}
  options         = default_options.update(options)
  Tire::Search::Multi::Search.new(index.name, options, &block).results
end

#search(*args, &block) ⇒ Object

Returns search results for a given query.

Query can be passed simply as a String:

Article.search 'love'

Any options, such as pagination or sorting, can be passed as a second argument:

Article.search 'love', :per_page => 25, :page => 2
Article.search 'love', :sort => 'title'

For more powerful query definition, use the query DSL passed as a block:

Article.search do
  query { terms :tags, ['ruby', 'python'] }
  facet 'tags' { terms :tags }
end

You can pass options as the first argument, in this case:

Article.search :per_page => 25, :page => 2 do
  query { string 'love' }
end

This methods returns a Tire::Results::Collection instance, containing instances of Tire::Results::Item, populated by the data available in _Elasticsearch, by default.

If you'd like to load the "real" models from the database, you may use the :load option:

Article.search 'love', :load => true

You can pass options as a Hash to the model's find method:

Article.search :load => { :include => 'comments' } do ... end
