Second tier searchengines

Second tier searchengines

I don't see them discussed much. What are they? Some wafo wso guy claims to have a bot that searches 20 of them, I can't think of one (what I imagine them to be, rebranded searchfunctions). Anyone know where they can be found?

Discuss.

Where would I get a script like this? I would put it on a page and send shit traffic to it and every visitor would search the interwebs for me while they're on my page?
