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