• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) OR (so sach)) ty lang xa hoi. hieu ve huu phuc va thanh vai ((cua tre) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) ty lang xa hoi. hieu ve huu phuc va thanh vai ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (so sach)) ty lang xa hoi. hieu ve huu phuc va thanh vai ((cua tre) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: ((su sach) OR (so sach)) ty lang xa hoi. hieu ve huu phuc va thanh vai ((cua tre) or (cua te))*.
