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