• Performing a fuzzy search may retrieve terms with similar spellings: ((doi chieu) OR (ho chieu)) sach - thanh dung qua dung cong tac ((nhanh cau) or (thanh chu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((doi chieu) OR (ho chieu)) sach - thanh dung qua dung cong tac ((nhanh cau) OR (thanh chu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chieu) OR (ho chieu)) sach - thanh dung qua dung cong tac ((nhanh cau) or (thanh chu))".
• Adding a wildcard symbol may retrieve word variants: ((doi chieu) OR (ho chieu)) sach - thanh dung qua dung cong tac ((nhanh cau) or (thanh chu))*.
