• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ly ((lang xa) or (((hoang xa) OR (hoang ha)))) hoi. hieu van hac duc va thanh lai cau triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ly ((lang xa) OR (((hoang xa) OR (hoang ha)))) hoi. hieu van hac duc va thanh lai cau triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ly ((lang xa) or (((hoang xa) OR (hoang ha)))) hoi. hieu van hac duc va thanh lai cau triet".
• Adding a wildcard symbol may retrieve word variants: tu sach ly ((lang xa) or (((hoang xa) OR (hoang ha)))) hoi. hieu van hac duc va thanh lai cau triet*.
