• Performing a fuzzy search may retrieve terms with similar spellings: te sach kho ((lang ha) OR (long ha)) hoi. hieu ve cham duc ban ((thanh va) or (thanh van)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach kho ((lang ha) OR (long ha)) hoi. hieu ve cham duc ban ((thanh va) OR (thanh van)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach kho ((lang ha) OR (long ha)) hoi. hieu ve cham duc ban ((thanh va) or (thanh van)) cuu tre".
• Adding a wildcard symbol may retrieve word variants: te sach kho ((lang ha) OR (long ha)) hoi. hieu ve cham duc ban ((thanh va) or (thanh van)) cuu tre*.
