• Performing a fuzzy search may retrieve terms with similar spellings: (( tu sach dao ve gioi con hong tien ) or ( tu cac che my ((gioi cau) OR (gioi cam)) thong tienh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach dao ve gioi con hong tien ) OR ( tu cac che my ((gioi cau) OR (gioi cam)) thong tienh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach dao ve gioi con hong tien ) or ( tu cac che my ((gioi cau) OR (gioi cam)) thong tienh ))".
• Adding a wildcard symbol may retrieve word variants: (( tu sach dao ve gioi con hong tien ) or ( tu cac che my ((gioi cau) OR (gioi cam)) thong tienh ))*.
