Add the ability to use "special" characters (@, #, etc) when using searching in "Top Queries"

Hi, I'm trying to search some query patterns on the "Top Queries" grid for example "INSERT INTO @" or "INSERT INTO #" (to get all inserts on table variables or temp tables) however, in both situations, the @ and the # is being ignored.

Please include those (and other chars) to refine our searches.

Not sure if "RegEx" would be another option that would be even broader.
