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