LimeWire PRO Really Give More Search Results?
 

I just downloaded LimeWire Pro, which says:

"Better Search Results"

"Turbo-charged download speeds"

"Connect To More Sources" etc., etc.

But, when I tried searching for a song, I found that I got less search results, same download speeds. Any thoughts on why?

First of all, if you were already using your entire bandwidth (or close) with Basic, then the only way to get faster speeds is to upgrade your connection. No application (Pro included) will give you faster speeds.
Second, Pro connects to more people, thus you should be getting results with more hosts, which should get you better/more accurate reults with more stars or hosts.

Well, then doesn't LimeWire lie about its program? And isn't that false advertising? I have a 2.5Mbit down connection, so I guess its not going to get much faster.

Marketing...
It's not really a lie: you will get high speeds (if you know how to configure LW and what/how to download) but the most you will ever get is a little less than what your bandwidth (as your ISP advertises it) says.
Again, there is only one way to get faster speeds than what you pay for: pay for more...
