• Performing a fuzzy search may retrieve terms with similar spellings: thu sach thi hang ca hoi. hieu va cac nuoc van manh dao ((((cua te) OR (cua tu))) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach thi hang ca hoi. hieu va cac nuoc van manh dao ((((cua te) OR (cua tu))) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach thi hang ca hoi. hieu va cac nuoc van manh dao ((((cua te) OR (cua tu))) or (cuu tre))*".
