• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((thuyet danh) OR (thuyet dan)) - ((thanh trung) or (thanh tung)) cua truong cong dan toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thuyet danh) OR (thuyet dan)) - ((thanh trung) OR (thanh tung)) cua truong cong dan toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thuyet danh) OR (thuyet dan)) - ((thanh trung) or (thanh tung)) cua truong cong dan toan cau".
• Adding a wildcard symbol may retrieve word variants: hoc ((thuyet danh) OR (thuyet dan)) - ((thanh trung) or (thanh tung)) cua truong cong dan toan cau*.
