• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach bai me gioi song thong tin ) OR ( te sach ((ha van) OR (va van)) cua cong hoang minh ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach bai me gioi song thong tin ) or ( te sach ((ha van) OR (va van)) cua cong hoang minh ))~".
• Adding a wildcard symbol may retrieve word variants: (( tu sach bai me gioi song thong tin ) or ( te sach ((ha van) OR (va van)) cua cong hoang minh ))*.
