Subject Re: Documents to query
Date Mon, 24 Nov 2014 19:02:52 GMT
Is this the "Paris - France + Italy = Rome" thing? I think I've seen a
couple of discussions about that.

When you say a "term" are you actually looking for one keyword?
Because that's very different from a query that can be infinitely
complex.
