#search_definition ⇒ Object
Returns the value of attribute search_definition.
Instance Method Summary collapse
-
#active_records(relation) ⇒ Object

-
#documents(document_klass) ⇒ Object
Performs the search using the default search type and returning an iterator that will yield each document, converted to the provided document_klass.
-
#initialize(client, search_definition) ⇒ Facade
constructor
Creates a new facade for the given search definition, providing a set of helper methods to trigger different type of searches and results interpretation.
-
#scan_documents(document_klass, **options) ⇒ Object
Performs the search using the scan search type and the scoll api to iterate over all the documents as fast as possible.
