I'm honestly not sure. I haven't really used presearch more than a handful times, max. That being said, it seems like a decent search engine and it seems to rank my leofinance article at the top as well when I'm searching for it, so that's a good thing.. :P
Great question though! I wish I had a better answer for you.

It's ok. I like it because I can use it as a search engine and if it doesn't work out, I can just swap it to google afterwards with a click.
