Search bbPress extends WordPress’ native search to include bbPress post types allowing WordPress to automatically include bbPress content in results. Link adjustments are made to results to ensure users will be taken directly to replies, topics, and forums. This plugin also fixes the double quote typo in bbPress’ unified login widget.
Simply activate to add the power of search to your forum.

<h3>Additional Info</h3>
Purpose: What good is a forum without search? Our plugin addresses this issue. You may already know that WordPress is an expert on taxonomy and already handles posts, tags, and parent-to-child page hierarchy beautifully. But search is missing on the front end; where it matters to your visitors. My Search bbPress plugin takes care of this and promotes forum participation with links that take them to the heart of their search terms. Have your bbPress implementation deliver search results that matter!
