• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky lang ha hoi. thien van ban duc va ((hanh hai) or (nhanh ha)) ((cua te) OR (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky lang ha hoi. thien van ban duc va ((hanh hai) OR (nhanh ha)) ((cua te) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky lang ha hoi. thien van ban duc va ((hanh hai) or (nhanh ha)) ((cua te) OR (cua tu))".
• Adding a wildcard symbol may retrieve word variants: su sach ky lang ha hoi. thien van ban duc va ((hanh hai) or (nhanh ha)) ((cua te) OR (cua tu))*.
