• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky ((nang ma) OR (tang ma)) hoi. hieu vu cham xuc ((va danh) or (va tinh)) cau cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((nang ma) OR (tang ma)) hoi. hieu vu cham xuc ((va danh) OR (va tinh)) cau cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((nang ma) OR (tang ma)) hoi. hieu vu cham xuc ((va danh) or (va tinh)) cau cua te".
• Adding a wildcard symbol may retrieve word variants: te sach ky ((nang ma) OR (tang ma)) hoi. hieu vu cham xuc ((va danh) or (va tinh)) cau cua te*.
