Hi ... I'm not sure you need a developer to answer
If you download a file showing 20 hosts and you share the file, then the file will show 21 hosts to other users (your copy will not show up on your machine) (in theory)
At different times different hosts will be on line and you will only see the files for the online hosts (more or less
) So your search may only show up one sourse for a file , 10 minutes later, or after restarting Limewire you may get a diffrent number. It depends on your connections, ... you cannot see all the files on the entire network, ....on who is on line etc
In short you can only see what is currently available and this can vary from minute to minute and connection to connection. I hope this helps
