• If you are trying to use Boolean operators, they must be ALL CAPS: (( su sach xa ca ((nguoi bo) OR (nguoi co)) hoang minh ) OR ( su sach ba me gio hop hoan minh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( su sach xa ca ((nguoi bo) OR (nguoi co)) hoang minh ) or ( su sach ba me gio hop hoan minh ))".
• Adding a wildcard symbol may retrieve word variants: (( su sach xa ca ((nguoi bo) OR (nguoi co)) hoang minh ) or ( su sach ba me gio hop hoan minh ))*.
