• Performing a fuzzy search may retrieve terms with similar spellings: tu sach tai dang van hoi. ((hieu ve) or (lieu va)) nhan luc va hanh vai ((cuu tre) OR (cua tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach tai dang van hoi. ((hieu ve) OR (lieu va)) nhan luc va hanh vai ((cuu tre) OR (cua tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach tai dang van hoi. ((hieu ve) or (lieu va)) nhan luc va hanh vai ((cuu tre) OR (cua tre))*".
