I have an index which, when searched with this query ("cloning clone animal") produces
1103 hits. A different, more narrow query ("(cloning clone) AND animal") produces
only 19 hits.
What's puzzling to me is that if I try a different (but supposedly identical) form of
the more narrow query ("+(cloning clone) +animal"), it produces 1103 hits rather than
the 19 that I expect.
In other words, "+(cloning clone) +animal" appears to be the equivalent of "cloning OR
clone OR animal" rather than "(cloning OR clone) AND animal".
Am I misunderstanding something about the "+ -" syntax, or is this some kind of bug?
Regards,
Terry
