The subtle part is that a scoring system is being used that operates in something of a boolean fashion, but that has subtle difference.
Mark, -thank you-. This explains it beautifully. So, if I understand you right, a simple query of NOT ORANGES gets me every document that does not contain the word oranges, while a separate query with -ORANGES added will force the score to zero for all documents in which oranges does not appear. One's a selector, the other is a filter. The + operator, in turn, simply affects the score (which is used for ranking). Anything with a non-zero score is returned, but the better the score, the more prominent it is in the ordered result list. Do I have correct and complete understanding of the two operators? -wls
