Normal Search
A match is found when ANY of the keywords are present in a document. The documents are ordered from the highest match count, to to the lowest and is reflected in the relevance score.
Advanced Search
An advanced search lets you modify the search parameters, using the following special characters:
| + | A leading plus sign indicates that this word MUST be present to form a match. |
| - | A leading minus sign indicates that this word MUST NOT be present to form a match. |
| > < | These two operators are used to change a word's contribution to the relevance value that is assigned to a match. The > increases the contribution and the < decreases it. |
| ( ) | Parentheses are used to group words into subexpressions. Parenthesised groups can be nested. |
| ~ | A leading tilde acts as a negation operator, causing the word's contribution to the match relevance to be negative. A match 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. |
| " | A phrase that is enclosed within double quotes, eg "a phrase", will form a match only if that entire phrase is present. |
