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