[Web4lib] search engine question

[Isabel Danforth]

I am looking for a search engine that produce a set of threads as a result 
of a query. I know that there is one, but cannot locate it in my files.

For example - perform a search on the world mercury

It would produce a list of links related to mercury the planet, mercury the 
car, mercury the god, etc.

Can anyone point me to such a search engine/
