There's a bug -- searching on Item Text matches wildcard doesn't work for items whose associated extension is not configured to be keyworded (.rtf in this case).
The latest download (
http://www.kinook.com/Download/UltraRecallProEval.exe; UltraRecall.exe version 3.1.1.5 in Help | About | Install Info after installing) has been updated with a fix for this issue. With the fix, the Item Text matches wildcard search will find the SEARCH THIS item even if .rtf is not in the extensions to keyword list.
