This is a tough one because I've got a few different plugins installed and I'm not sure if any are effecting this issue.
Basically, on the edit posts page, I need to do a lot of batch tagging from search results. I've tried to get it so the search hits all my custom fields, but a lot of times it doesn't even seem to find results from the post title. It's also fairly finicky, not finding anything if there is a trailing space or something like that.
Is there any plugin for a more powerful admin search? Is there some kind of backend problem I'm encountering?
I use a WP Custom Search widgit for the actual page search and it works excellent for finding results - there's gotta be some way to get similar kind of results in the backend.
