Module: Tire::Model::Search

Defined in:
lib/tire/model/search.rb

Overview

Main module containing the search infrastructure for ActiveModel classes.

By including this module, you'll provide the model with facilities to perform searches against index, define index settings and mappings, access the index object, etc.

All the Tire methods are accessible via the "proxy" class and instance methods of the model, named tire, eg. Article.tire.search 'foo'.

When there's no clash with a method in the class (your own, defined by another gem, etc) Tire will bring these methods to the top-level namespace of the class, eg. Article.search 'foo'.

You'll find the relevant methods in the ClassMethods and InstanceMethods module.

Defined Under Namespace

Modules: ClassMethods, InstanceMethods, Loader Classes: ClassMethodsProxy, InstanceMethodsProxy
