Boolean Searches
The following examples demonstrate some search strings that use boolean operators:
- design community
Find rows that contain at least one of the two words. - +design +community
Find rows that contain both words. - +design community
Find rows that contain the word “design”, but rank rows higher if they also contain “community”. - +design -community
Find rows that contain the word “design” but not “community”. - +design ~community
Find rows that contain the word “design”, but if the row also contains the word “community”, rate it lower than if row does not. - +design +(>community <decisions)
Find rows that contain the words “design” and “community”, or “design” and “decisions” (in any order), but rank “design community” higher than “design decisions” - design*
Find rows that contain words such as “design”, “designs”, “designing”, or “designer”. - "some words"
Find rows that contain the exact phrase “some words” (for example, rows that contain “some words of wisdom” but not “some noise words”). Note that the " characters that enclose the phrase are operator characters that delimit the phrase. They are not the quotation marks that enclose the search string itself.
