FYI
Advanced queries support the following operators:
+ A leading plus sign indicates that this word must be present in every result returned.
- A leading minus sign indicates that this word must not be present in any result returned.
< > These two operators are used to change a word's contribution to the relevance value that is assigned to a result. The < operator decreases the contribution and the > operator increases it. See the example below. The relevance of a result only matters if you choose to sort by it.
~ A leading tilde acts as a negation oeprator, causing the word's contribution to the row relevance to be negative. It's useful for marking noise words. A row that contains such a word will be rated lower than others, but will not be excluded altogether, as it would be with the - operator.
* An asterisk is the truncation operator. Unlike the other operators, it should be appended to the word, not prepended.
" The phrase, that is enclosed in double quotes, matches only the results that contain this phrase literally, as it was typed.
And here are some examples:
apple banana
find rows that contain at least one of these words.
+apple +juice
... both words.
+apple macintosh
... word "apple", but rank it higher if it also contains "macintosh".
+apple -macintosh
... word "apple" but not "macintosh".
+apple +(>pie <strudel)
... "apple" and "pie", or "apple" and "strudel" (in any order), but rank "apple pie" higher than "apple strudel".
apple*
... "apple", "apples", "applesauce", and "applet".
"some words"
... "some words of wisdom", but not "some noise words".
