eg/ using simple search in OPAC QueryWeightFields (enabled) flute AND oboe = 701 flute OR oboe = 115 flute NOT oboe = 10 QueryWeightFields (disabled) flute AND oboe = 1038 flute OR oboe = 3983 flute NOT oboe = 2121 The results from the "disabled" look correct but of course there is no longer any relevance ranking.
It should do some kind of relevance ranking without. Debugging search issues is hard, but what I would recommend is doing your testing again with and without QueryAutoTruncate - there is a known bug of it breaking relevance.

With QueryWeightFields on, boolean are considered like string, on purpose. The search terms are around quotes.
I think that this is a duplicate of Bug 12430 *** This bug has been marked as a duplicate of bug 12430 ***
