 Priority:  normal          |  Milestone:  3.7
Component:  Query           |    Version:  trunk
 Severity:  normal          |   Keywords:  has-patch
----------------------------+-----------------------
 As [http://wordpress.org/support/topic/behavior-of-the-posts_search-
 filter-has-changed reported on the forums], [25632] changed the behaviour
 of the `posts_search` filter.

 In 3.6, the filter is applied unconditionally, even when the `'s'` query
 var is empty.

 In 3.7-RC1, the filter has been moved into `WP_Query::parse_search()`,
 which is only executed if `$q['s']` is not empty, so a plugin cannot add a
 search clause to a query if it doesn't have one.
