• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (doc hieu)) xanh - hanh trinh thuat nhung cong ((danh toan) OR (dan toan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (doc hieu)) xanh - hanh trinh thuat nhung cong ((danh toan) OR (dan toan)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (doc hieu)) xanh - hanh trinh thuat nhung cong ((danh toan) OR (dan toan)) cau*.
