• Performing a fuzzy search may retrieve terms with similar spellings: theo co sach - ((thanh truong) OR (thanh tung)) dai hung xuong dan ((than cau) or (thanh cac))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo co sach - ((thanh truong) OR (thanh tung)) dai hung xuong dan ((than cau) OR (thanh cac))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo co sach - ((thanh truong) OR (thanh tung)) dai hung xuong dan ((than cau) or (thanh cac))*".
