The number of hits that you see shows how many times your files have appeared in someone's search results... it doesn't necessarily mean that people are looking for the exact files that you're sharing.

The network's search isn't too precise - say if you search for 'the black cat', you'd see results for 'the cat', 'the black', 'black cat', 'black', 'cat' etc etc... so other people might have only 1 keyword in their search results that appears in one of your files - but it can still show as a hit.
Hope that makes sense

If you're behind a firewall, some people may be able to 'push' through your firewall to download, but chances are most won't be able to.
Just because you can download, doesn't mean that others can download from you
