• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sang)) - thanh trung van ((dong cong) OR (dang cong)) van thanh cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sang)) - thanh trung van ((dong cong) or (dang cong)) van thanh cau".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sang)) - thanh trung van ((dong cong) or (dang cong)) van thanh cau*.
