No I don't work for LW. Nor do I get paid for helping out on the forum.
A manual search is simply using the search function. Type in the words of what you're looking for & press search.
The reason I was applauding you prabato is b/c too many requeries with using the resume/find sources function makes too much traffic for the gnutella network. If everybody did that every few mins then the network would slow down due to too much traffic. Then all our downlds & searches would be very slow.
