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