• If you are trying to use Boolean operators, they must be ALL CAPS: chao ((chu manh) OR (chu han)) - thanh ((trung phan) OR (trung thanh)) thong cong dan can cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "chao ((chu manh) or (chu han)) - thanh ((trung phan) OR (trung thanh)) thong cong dan can cau".
