• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (te sach)) ly sang ma hoa. ((hieu ve) or (hieu va)) cau luc va tinh gia cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ly sang ma hoa. ((hieu ve) OR (hieu va)) cau luc va tinh gia cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) ly sang ma hoa. ((hieu ve) or (hieu va)) cau luc va tinh gia cua tre".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (te sach)) ly sang ma hoa. ((hieu ve) or (hieu va)) cau luc va tinh gia cua tre*.
