• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho nhieu) OR (hop nhieu)) tang - hanh tran van phuong ((cong tan) OR (cong tac)) toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho nhieu) or (hop nhieu)) tang - hanh tran van phuong ((cong tan) OR (cong tac)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((ho nhieu) or (hop nhieu)) tang - hanh tran van phuong ((cong tan) OR (cong tac)) toan ban*.
