• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky sang tai hai. ((hieu ve) OR (hieu van)) cam xuc ((va danh) or (va thanh)) vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky sang tai hai. ((hieu ve) OR (hieu van)) cam xuc ((va danh) OR (va thanh)) vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky sang tai hai. ((hieu ve) OR (hieu van)) cam xuc ((va danh) or (va thanh)) vi cua te*".
