• Performing a fuzzy search may retrieve terms with similar spellings: ho ((((chieu tinh) OR (trieu tinh))) or (chieu sach)) - thanh trung van dung cong tan tran cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((((chieu tinh) OR (trieu tinh))) OR (chieu sach)) - thanh trung van dung cong tan tran cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((((chieu tinh) OR (trieu tinh))) or (chieu sach)) - thanh trung van dung cong tan tran cau*".
