• If you are trying to use Boolean operators, they must be ALL CAPS: chao ((chieu xanh) OR (chieu tinh)) - hanh tang cua thong cong tac ((chinh ta) OR (chinh va))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "chao ((chieu xanh) OR (chieu tinh)) - hanh tang cua thong cong tac ((chinh ta) or (chinh va))~".
• Adding a wildcard symbol may retrieve word variants: chao ((chieu xanh) OR (chieu tinh)) - hanh tang cua thong cong tac ((chinh ta) or (chinh va))*.
