Logical Operators
+ - AND NOT OR
Logical operators use the principles of Boolean logic to focus search queries.
For example, entering either
fish -sharks or fish NOT sharks
would return results relating to fish but excluding sharks.
Entering either
fish +sharks or fish AND sharks
would return results relating to primarily shark-related sites.
Entering
cats OR dogs
would return results containing subject matter on either cats or dogs.
