• Performing a fuzzy search may retrieve terms with similar spellings: su sach y dang lap hoat. hieu ve ((cam luc) OR (cau luc)) ((va danh) or (va hanh)) vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y dang lap hoat. hieu ve ((cam luc) OR (cau luc)) ((va danh) OR (va hanh)) vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y dang lap hoat. hieu ve ((cam luc) OR (cau luc)) ((va danh) or (va hanh)) vi cua te".
• Adding a wildcard symbol may retrieve word variants: su sach y dang lap hoat. hieu ve ((cam luc) OR (cau luc)) ((va danh) or (va hanh)) vi cua te*.
