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