Boolean search options
When none of the following boolean options is specified, the search engine automatically puts a + in front of all words, which means that this word must be present in every row returned. The other options are:
| + | A leading plus sign indicates that this word must be present in every row returned. |
| - | A leading minus sign indicates that this word must not be present in any row returned. |
| < > | These two operators are used to change a word’s contribution to the relevance value that is assigned to a row. The < operator decreases the contribution and the > operator increases it. |
| ( ) | Parentheses are put round sub-expressions to give them higher precedence in the search. |
| ~ | A leading tilde acts as a negation operator, 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 minus operator. |
| * | An asterisk is the truncation operator. Unlike the other operators, it is appended to the word, or fragment, not prepended. |
| " " | Double quotes at the beginning and end of a phrase, matches only rows that contain the complete phrase, as it was typed. |
Boolean search examples
| schmid petra | find rows that contain at least one of these words. |
| +schmid +petra | find rows that contain both words. |
| +schmid petra | find rows that contain the word «schmid», but rank it higher if it also contain «petra». |
| +schmid -petra | find rows that contain the word «schmid» but not «petra». |
| +schmid +(>petra <pottery) | find rows that contain the word «schmid» and «petra», or «schmid» and «pottery» (in any order), but rank «schmid petra» higher than «schmid pottery». |
