• If you are trying to use Boolean operators, they must be ALL CAPS: (("su sach dinh tri") OR ((("tu sach danh tri") OR ("tu sach danh tu"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"su sach dinh tri\") or (((\"tu sach danh tri\") OR (\"tu sach danh tu\"))))*".
• Removing quotes may allow a broader search: (( su sach dinh tri ) or ((( tu sach danh tri ) OR ( tu sach danh tu ))))*.
