• Performing a fuzzy search may retrieve terms with similar spellings: hoc sach ky ((dang ma) OR (dang mam)) hoa. lieu ((va cam) or (va cac)) xuc ban hanh vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc sach ky ((dang ma) OR (dang mam)) hoa. lieu ((va cam) OR (va cac)) xuc ban hanh vai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc sach ky ((dang ma) OR (dang mam)) hoa. lieu ((va cam) or (va cac)) xuc ban hanh vai cua te*".
