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