It's usually not possible to find your own shared files in a search.

Do you see the firewall icon (brick wall in front of the blue globe)? People will have a hard time downloading from you if you're firewalled During your LW session, go to LW's library & check the uploads column...figure on the right shows attempted uploads & figure on the left shows successful uploads.
You can also go tools > options > bug reports > view example. Scroll down to 'recieved incoming this session' - if it's false then you're not recieving incoming connections from other computers (probably a firewall issue).
