Right now, whatever SQL LIKE expression passed in by the user is being shoved into the query for Nuke. A DBA has suggested that this isn't good practice; this is also pretty far off from what we normally use for wildcard matching. (typing in raw SQL on a production site isn't the best of ideas)

The filter should be replaced with something else: wildcard matching using *, RegExp, or something else. We can also just remove it entirely if it's unused, but we'd first need analytics on how frequently it gets used.
