• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu tinh) OR (chau tinh)) - lanh manh cua ((nhung cong) OR (thong cong)) dan van ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu tinh) OR (chau tinh)) - lanh manh cua ((nhung cong) or (thong cong)) dan van ban".
