• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ky lang mai hoi. ((hieu ve) OR (hieu va)) cam xuc va thanh dat ((cua te) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky lang mai hoi. ((hieu ve) OR (hieu va)) cam xuc va thanh dat ((cua te) OR (cua triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky lang mai hoi. ((hieu ve) OR (hieu va)) cam xuc va thanh dat ((cua te) or (cua triet))*".
