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