Using Parentheses to Specify the Order of Operators

You can enclose search terms and their operators in parentheses to specify the order that they are interpreted.

shots/sea90000.gif  Information within parentheses is read first, then information outside parentheses is read next.

shots/sea90000.gif  If there are nested parentheses, the search engine processes the innermost parenthetical expression first.

The following example is interpreted to mean: Find documents that contain vomit or diarrhoea as well as blood.

Nested Parentheses

If there are nested parentheses, the search engine processes the innermost parenthetical expression first, then the next, and so on until the entire query is interpreted.

The following example is interpreted to mean: Find documents that contain vomit or diarrhoea as well as blood, and any documents that contain phenol.
