At first I was going to ask about having [advanced search][1] (including all [options][2]), but then I realised that it was already there.

Even though I like the syntax, maybe an advanced search UI (well, it would be a simple page) that only assists users in entering *'[advanced super ninja search options][2]'* would make sense?
