Advanced search options
+word
A leading plus sign indicates that this word must be present in every row returned.
-word
A leading minus sign indicates that this word must not be present in any row returned.
<word | >word
These two operators are used to change a word's contribution to the relevance value that's assigned to a row. The > operator increases the contribution and the < operator decreases it. Refer to the example below.
()
Parentheses are used to group words into subexpressions. Parenthesised groups can be nested.
~word
A leading tilde acts as a negation operator, causing the words 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.
word*
An asterisk is the truncation operator. Unlike the other operators, it should be appended to the word, not prepended.
"word word"
A phrase that is enclosed within double quote characters matches only rows that contain the phrase literally, as it was typed.
Examples
The following examples demonstrate some search strings that use boolean full-text operators:
apple banana
Find rows that contain at least one of the two words.
+apple +juice
Find rows that contain both words.
+apple macintosh
Find rows that contain the word "apple", but rank rows higher if they also contain "macintosh".
+apple -macintosh
Find rows that contain the word "apple" but not "macintosh".
apple*
Find rows that contain words such as "apple", "apples", "applesauce", or "applet".
+apple +(>turnover <strudel)
Find rows that contain the words apple and "turnover", or "apple" and "strudel" (in any order), but rank "apple turnover" higher than "apple strudel".
