• Performing a fuzzy search may retrieve terms with similar spellings: thuat sach tu nano xa hoi. hieu ((ve cao) OR (ve cac)) duc va tinh ca ((cua te) or (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach tu nano xa hoi. hieu ((ve cao) OR (ve cac)) duc va tinh ca ((cua te) OR (cua tu))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach tu nano xa hoi. hieu ((ve cao) OR (ve cac)) duc va tinh ca ((cua te) or (cua tu))*".
