• If you are trying to use Boolean operators, they must be ALL CAPS: %22theory AND ((((((visual library) OR (visual literacy))) OR (virtual library))) OR (gson library))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22theory and ((((((visual library) OR (visual literacy))) or (virtual library))) or (gson library))%22".
• Adding a wildcard symbol may retrieve word variants: %22theory and ((((((visual library) OR (visual literacy))) or (virtual library))) or (gson library))%22*.
