Nested Queries
You can enclose search terms and their operators in parentheses to specify the
order that they are interpreted. Information within parentheses is read first,
then information outside parentheses is read next. The following example is
interpreted to mean: Find pages that match adobe or cognisoft as well as verity.
Note
In contrast to the
previous example, this query produces 96 matching pages (rather than 97) because the file
back.doc contains cognisoft but not verity.
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 pages that
match adobe or cognisoft as well as verity or pages that match intel.
