spinning time
 

is there any way on lime wire to increase spinning time in order to get more results per search?

Sometimes even if the searches seems finished, additional results will keep adding themselves.
Besides, it may not be a very good idea to wait for too long: if you want to have like 500 results and have to wait like 5 minutes for those, then maybe the results that have already appeared will no longer be valid after the search finishes, due to people logging in and out during those 5 minutes.
