4. Using More than One Search Operator

You may use many of the basic operators and search operators with each other. However, there are some that must be used by themselves and others that you should be careful about using together.

Search Operators that Can’t Be Combined

There are about a dozen search operators that can’t be combined with any other. If you do, Google probably won’t return any matching documents. Search operators that shouldn’t be mixed include:

• All the search operators whose names begin with “allin,” e.g., allinanchor:, allintext:, allintitle:, and allinurl:.
• Syntaxes that request special information, e.g., define:, phonebook, rphonebook, stocks:.
• Page-specific search operators, e.g., cache:, info:, related:.
