I just create a notepad document with a list of common keywords I want to search for on a regular basis. Or even when limewire isn't running and I want to search for something I write a list that I want to search for. So when I start I just highlight the keyword in notepad CTRL-C (copy) then CTRL-V (paste) into the search window as I have limewire and the notepad windows side by side. I can get a dozen in 30 seconds. That's my method.
I do that more for remembering what I want to search for. I'm not that lazy that I can't type.
