• Performing a fuzzy search may retrieve terms with similar spellings: hoc chieu xanh - hanh ((trang van) OR (trong van)) nhuong cong ((manh toan) or (thanh toan)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu xanh - hanh ((trang van) OR (trong van)) nhuong cong ((manh toan) OR (thanh toan)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - hanh ((trang van) OR (trong van)) nhuong cong ((manh toan) or (thanh toan)) cau*".
