• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu xanh) OR (chieu sach)) - hang doanh luan nhung cong van ((thanh chau) OR (nhanh cay))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) OR (chieu sach)) - hang doanh luan nhung cong van ((thanh chau) or (nhanh cay))~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu xanh) OR (chieu sach)) - hang doanh luan nhung cong van ((thanh chau) or (nhanh cay))*.
