Actually, it's using a weighted/scoring algorithm which ranks A AND B higher
than A OR B, while considering both implicitly.
That is, if you enter "foo bar", then the order of things returned is
roughly:
- First, articles containing both "foo" and "bar" and containing them near
each other and/or near the top of the document,
- Next, articles containing both "foo" and "bar" anywhere,
- And finally, articles containing either "foo" or "bar".
But it's a numerical weighting/scoring method, so an article with "foo blah
bar" at word-position 18 may score lower than an article with "foo blah blah
blah bar" at word-position 10; or an article with "foo" in the first 3 words
but not "bar" anywhere might score higher than an article with "foo" at
word-position 300 and bar at word-position 400.
Anyway, it does its best to consider word pairs as being more important than
single separate words, but I agree that something more sophisticated would
really be nice.

I really like the way AltaVista lets you use double-quotes (") and plus-
signs (+) and minus signs (-). Something like that?

What about specifying a target date? That's something I want. I want to be
able to say, "Anything that's about 2 weeks old, give that a higher score
than the other results," or "Give the very newest stuff (say, stuff that's
about 0 hours old) a higher score than the other results." This would help
me dig up old threads better when I knew a couple of the words that appeared
and the approximate date that they appeared on. (I don't like the way
DejaNews restricts things to a hard-edged date range...I like everything
fuzzy :-)

| (...) That's weird; I sometimes see results with just A or just B above results with both A and B. e.g., search for "Lego Maniac", and I see two results with just "Lego", one with "Lego - Maniac", one with "Lego", etc. Plus, there are times when I (...)
