• If you are trying to use Boolean operators, they must be ALL CAPS: cho ((chua xang) OR (chieu xanh)) - ((hanh tang) OR (anh tang)) luan nhung cong manh toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho ((chua xang) or (chieu xanh)) - ((hanh tang) OR (anh tang)) luan nhung cong manh toan cau~".
• Adding a wildcard symbol may retrieve word variants: cho ((chua xang) or (chieu xanh)) - ((hanh tang) OR (anh tang)) luan nhung cong manh toan cau*.
