• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty sang ((lap hai) OR (lap tai)). hieu ve cac xuc ((va danh) or (van dinh)) di cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty sang ((lap hai) OR (lap tai)). hieu ve cac xuc ((va danh) OR (van dinh)) di cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty sang ((lap hai) OR (lap tai)). hieu ve cac xuc ((va danh) or (van dinh)) di cua te".
• Adding a wildcard symbol may retrieve word variants: su sach ty sang ((lap hai) OR (lap tai)). hieu ve cac xuc ((va danh) or (van dinh)) di cua te*.
