Try "-lw exam". FARR plugin uses locate.exe with searches so you can use its command line arguments (see "locate -h" in command prompt).
For Locate32, I suggest you to try "Match whole name only" option in Advanced tab.

Thanks, jmj, for your reply!
Unfortunately your suggestions didn't work in my situation. The file name I'm looking for merely contains the word "exam", it is not the entire title. Using -lw, therefore, brings up no results.
As I mentioned, the Locate32 program itself works great! I can specify "exam -example" in my search and it will match all files containing "exam", but exclude just those that have "example". Neither the Locate32 plugin nor FARR seem to offer the same capabilities though (so far as I can tell). I consulted the list of command line arguments as you suggested, but I still don't see anything that works in this particular case. I hope I might be just missing something obvious!
I'd welcome any further suggestions you might have. Many thanks!
