|Operator ||Expected results||+ ||A leading plus sign indicates that this word must be present in every piece of information returned.
||- ||A leading minus sign indicates that this word must not be present in any piece of information returned.
||< > ||These two operators are used to change a word's contribution to the relevance value that is assigned to a piece of information. The << operator decreases the contribution and the >> operator increases it. See the example below.
||( ) ||Parentheses are used to group words into subexpressions.
||~ ||A leading tilde acts as a negation operator, causing the word's contribution to the information relevance to be negative. It's used for marking noise words. A piece of information 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 shooud be appended to the word, not prepended.
||" ||The phrase, that is enclosed in double quotes ", matches only pieces of information that contain this phrase literally, as it was typed.
