• Performing a fuzzy search may retrieve terms with similar spellings: ((theo trieu) OR (theo chieu)) tinh - manh trung ((thuat nhung) or (tuan duong)) cong manh toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo trieu) OR (theo chieu)) tinh - manh trung ((thuat nhung) OR (tuan duong)) cong manh toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo trieu) OR (theo chieu)) tinh - manh trung ((thuat nhung) or (tuan duong)) cong manh toan cao".
• Adding a wildcard symbol may retrieve word variants: ((theo trieu) OR (theo chieu)) tinh - manh trung ((thuat nhung) or (tuan duong)) cong manh toan cao*.
