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