• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ly ((((lang xa) OR (lang van))) or (nang x)) hoi. hieu tu chat luu van thanh vi su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ly ((((lang xa) OR (lang van))) OR (nang x)) hoi. hieu tu chat luu van thanh vi su triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ly ((((lang xa) OR (lang van))) or (nang x)) hoi. hieu tu chat luu van thanh vi su triet*".
