SearchWP bbPress Integration Extension
By default, bbPress registers it’s post types to be excluded from search. Use the SearchWP bbPress Integration Extension to allow SearchWP to include bbPress content in search results.
What’s most useful about this Extension is the ability to have search weight normally found in Replies actually count toward the Topic by enabling post parent attribution when configuring Replies:
When enabled, search results will point to the parent Topic instead of the single Reply, which is awesome.
This is an extension of SearchWP Plugin. As to use this extension, you need to first install SearchWP Plugin.
