• The words AND, OR and NOT may confuse the search; try adding quotes: "%22theory and ((((vision library) or (((((((visual lidar) OR (visual aids))) or (visual aid))) or (visual binary))))) or (gson library))%22".
• Adding a wildcard symbol may retrieve word variants: %22theory and ((((vision library) or (((((((visual lidar) OR (visual aids))) or (visual aid))) or (visual binary))))) or (gson library))%22*.
