Instance Method Details

#data_accessor_for(clazz) ⇒ Object

Get the data accessor that will be used to load a particular class out of persistent storage. Data accessors can implement any methods that may be useful for refining how data is loaded out of storage. When building a search manually (e.g., using the Sunspot#new_search method), this should be used before calling #execute(). Use the Sunspot::DSL::Search#data_accessor_for method when building searches using the block DSL.

  @registry ||= Sunspot::Adapters::Registry.new
  @registry.retrieve(clazz)
end

#each_hit_with_result ⇒ Object

Convenience method to iterate over hit and result objects. Block is yielded a Sunspot::Server::Hit instance and a Sunspot::Server::Result instance.

Note that this method iterates over verified hits (see #hits method for more information).

#populate_hits ⇒ Object

Populate the Hit objects with their instances. This is invoked the first time any hit has its instance requested, and all hits are loaded as a batch.
