• Performing a fuzzy search may retrieve terms with similar spellings: te sach 2 dang ma hoa. hieu va ((((nam duoc) OR (nam thuoc))) or (cam xuc)) va thanh hai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach 2 dang ma hoa. hieu va ((((nam duoc) OR (nam thuoc))) OR (cam xuc)) va thanh hai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach 2 dang ma hoa. hieu va ((((nam duoc) OR (nam thuoc))) or (cam xuc)) va thanh hai cua te".
• Adding a wildcard symbol may retrieve word variants: te sach 2 dang ma hoa. hieu va ((((nam duoc) OR (nam thuoc))) or (cam xuc)) va thanh hai cua te*.
