In my opinion, the bottom line is that context is king. My ideal
solution would be to quote the lines in which the keyword(s) appear
along with each search hit. I do not know how much of a performance/size
hit this would entail, nor how much extra programming it would entail. I
guess we'd store line numbers along with documents in the hashes?

Maybe it's an option which could be enabled in the, and turned
off by default.

Also, is there any way we could enable the user specifying boolean AND
and OR? I know the engine defaults to OR, but shouldn't the person be
able to stick an AND in to manually override it? I know we can achieve
the same effect using +, so AND shouldn't be that hard to stick in.
