• Performing a fuzzy search may retrieve terms with similar spellings: ((ho trieu) OR (mot trieu)) tinh - ((sinh truong) or (manh truong)) quan duong thuong van toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho trieu) OR (mot trieu)) tinh - ((sinh truong) OR (manh truong)) quan duong thuong van toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho trieu) OR (mot trieu)) tinh - ((sinh truong) or (manh truong)) quan duong thuong van toan cau*".
