| + |
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.
