def add_sphinx_scopes_support_to_has_many_associations

  ::ActiveRecord::Associations::HasManyAssociation.send(:include, scope_mixin)
  ::ActiveRecord::Associations::HasManyThroughAssociation.send(:include, scope_mixin)
end

#default_sphinx_scope(sphinx_scope_name) ⇒ Object

Similar to ActiveRecord’s default_scope method Thinking Sphinx supports a default_sphinx_scope. For example:

default_sphinx_scope :some_sphinx_named_scope

The scope is automatically applied when the search method is called. It will only be applied if it is an existing sphinx_scope.

end

#sphinx_scope(method, &block) ⇒ Object

Similar to ActiveRecord’s named_scope method Thinking Sphinx supports scopes. For example:

sphinx_scope(:latest_first) { 
    {:order => 'created_at DESC, @relevance DESC'}
  }

Usage:

@articles =  Article.latest_first.search 'pancakes'
