trying to search bug database

This is not a bug report for server but I don't see where I'm supposed to put it, If you can move it to the "right" place, please do.
I'm trying to find issues that were created by me, but under a previous user name (my old logins don't seem to work any more so I created a new account to look for bug reports). It's only slightly possible that I've never sent anything to the bug database before but not very plausible that there are NO bugs with reporter starting with "don" or "Don" - my email addr would have been don-[something]@isis.cs3-inc.com and my name would have been either Don or Donald Cohen. It seems you can't use "like" in the reporter field, and the suggestion was to start typing into the basic search, but that's showing no results. So how am I supposed to find these reports? Or do you claim there are none? At least by creating THIS report I should be able to find something, I hope.
