• Performing a fuzzy search may retrieve terms with similar spellings: ((doc hieu) or (ho chieu)) sang - hanh luong quan dung cong ((tan toan) OR (van toan)) tap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((doc hieu) OR (ho chieu)) sang - hanh luong quan dung cong ((tan toan) OR (van toan)) tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doc hieu) or (ho chieu)) sang - hanh luong quan dung cong ((tan toan) OR (van toan)) tap*".
