Enable SimpleSearch box in locked searches
 

If you LOCK a search/filter then you can't search within that filter.

However, you are showing a combo box above the buttons (start/reset, etc.) in the Filter. But it's disabled.

How about enabling it and allowing the user to search for keywords within that filter. (As if you were adding another search criteria (AND Keywords contain ___).

Oh, and it would be GREAT if the focus automtaically wen to that "Search for:" combo box.
