Say I have 1,257 JPEG files in my share directory. If I limit the responses to just 50, does Gnotella always give out the same tired old batch of 50 to the same search string match repeatedly?

If it does, that is am awfil waste of the other 1,207 JPEG's. I'd like to be sure that I can limit the responses to fifty but that, over time, the file mix distributed evens out to cover all of them.
