• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chau tinh)) - hanh ((trung do) OR (trung co)) dung cong ban chan cap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chau tinh)) - hanh ((trung do) OR (trung co)) dung cong ban chan cap".
