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