Instance Method Details

#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.

Usage:

@articles =  Article.latest_first.search 'pancakes'
