See the Search Attachments page on this site and the d.o. project page for details.
Thanks to lee20 for taking over this project.
Many users of search_attachments have requested being able to have search results from both node content and files in a single tab, as opposed to having separate tabs for each. Currently, any module that calls hook_search() and do_search(), both of which search_attachments does because it uses the core index tables, gets its search results placed in a separate tab.
I've updated the screencaps to show version 5.x-4. I'll be revising the other documentation over the next few days.
Drupal user mroswell has created a screencast on installing search_attachments 5.x-4. Very cool!
Please note: This module is no longer supported. Drupal 6 users are encouraged to use Search Files, which incorporates much of the funcationality of Search Attachments.

In order to make search_attachments respect access permissions better, I need to know what modules and/or access control configurations people are using to restrict access to nodes that files might be attached to.
