Search results pane: intelligent refresh

[quant]

My DB is growing at a steady pace, and even though everything is indexed, the searches are becoming a bit slow, sometimes say 10,20,30 seconds ... this is fine (well, not really, but can it be faster?).

What is not fine, is that as I scroll the search results while the search is still active, when new item if found, UR brings me at the beginning of the results. This is very bad, and in effect, I have to wait till the search finishes because it's impossible to scroll down and see whether something I'm looking for is already found.

It would be nice, if UR respects the last visible (or middle) item in the pane and update the pane, together with scrollbar bar, accordingly.

Or maybe someone has better idea?
