• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chu) OR (cho chu)) xanh - hanh tang luan thong cong ((dan toan) OR (van thanh)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chu) OR (cho chu)) xanh - hanh tang luan thong cong ((dan toan) or (van thanh)) cao~".
• Adding a wildcard symbol may retrieve word variants: ((theo chu) OR (cho chu)) xanh - hanh tang luan thong cong ((dan toan) or (van thanh)) cao*.
