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