• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ty tang ma hoi. hieu ve ((cac toc) OR (cac toi)) xa hang di ((cua te) or (cua tuc))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty tang ma hoi. hieu ve ((cac toc) OR (cac toi)) xa hang di ((cua te) OR (cua tuc))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty tang ma hoi. hieu ve ((cac toc) OR (cac toi)) xa hang di ((cua te) or (cua tuc))*".
