If you are using orban's code, it uses the regular vb searching for keywordless username searches and sphinx for everything else. If you have a smaller post table, you may not notice problems with it. Unfortunately, I had to remove anything that didn't use sphinx because my post table is a monster.

Regarding adding that keyword, that would require modification of orban's code as well as search.php; I don't have enough grasp on the code to make those modifications.
