• Performing a fuzzy search may retrieve terms with similar spellings: su sach y sang ma hoi. lieu van ((tham soc) or (thai son)) va danh vi ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y sang ma hoi. lieu van ((tham soc) OR (thai son)) va danh vi ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y sang ma hoi. lieu van ((tham soc) or (thai son)) va danh vi ((cua tre) OR (cua te))".
• Adding a wildcard symbol may retrieve word variants: su sach y sang ma hoi. lieu van ((tham soc) or (thai son)) va danh vi ((cua tre) OR (cua te))*.
