Logical Operators in Search Expressions
Logical operators are used to specify how multiple search terms are combined in a search query. Logical operators also create more complicated search expressions from simpler ones, and thus refine your search. The following table shows you how to use each of the available operators.
Logical operators must be entered in all capital letters for the search engine to recognize them.
