• If you are trying to use Boolean operators, they must be ALL CAPS: (( su ((sach 2ho) OR (sach dao)) loi gioi cong hong minh ) OR ( te sach 2 va doi dong hoc minh ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( su ((sach 2ho) OR (sach dao)) loi gioi cong hong minh ) or ( te sach 2 va doi dong hoc minh ))~".
• Adding a wildcard symbol may retrieve word variants: (( su ((sach 2ho) OR (sach dao)) loi gioi cong hong minh ) or ( te sach 2 va doi dong hoc minh ))*.
