I used to get a lot of search results but now get hardly any. I read

'The latest versions of LimeWire will designate you as either a "Leaf" or an "Ultrapeer". If you are a leaf shielded by an ultrapeer, you will not be able to see all the search terms being sent to the network. However, if you are an ultrapeer, you will see a constant stream of search terms in the Monitor window.'

What exactly does this mean and how can I get back to getting more search results please?
