Boolean search operators |
|
|
|
For locations marked *, this search engine supports complex and boolean searches. You can use:
|
|
+
|
: |
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. In other words, can not search for words ending on a fragment.
|
|
" "
|
: |
Double quotes at the beginning and end of a phrase, matches only rows that contain the complete phrase, as it was typed.
