• If you are trying to use Boolean operators, they must be ALL CAPS: ((mot chieu) OR (ho chieu)) xanh - hanh trung voi ((nhung duong) OR (nhung huong)) manh toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((mot chieu) or (ho chieu)) xanh - hanh trung voi ((nhung duong) OR (nhung huong)) manh toan cao".
• Adding a wildcard symbol may retrieve word variants: ((mot chieu) or (ho chieu)) xanh - hanh trung voi ((nhung duong) OR (nhung huong)) manh toan cao*.
