You can right click a search result after it stops searching and choose find more results, but apart from that I don't think there is much more you can do except search again.

BTW in this case it was a general Limewire question, so those thinks weren't really needed, but it's a joy to see that some people actually post the info we ask for

If it was a connection or download/upload problem, as in not able to download at all or most of the time, then they would be needed.
