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