• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky ((dang ma) OR (dang mam)) hoa. hieu ((van dam) or (van cau)) duc va hanh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((dang ma) OR (dang mam)) hoa. hieu ((van dam) OR (van cau)) duc va hanh vai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((dang ma) OR (dang mam)) hoa. hieu ((van dam) or (van cau)) duc va hanh vai cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky ((dang ma) OR (dang mam)) hoa. hieu ((van dam) or (van cau)) duc va hanh vai cua tre*.
