• If you are trying to use Boolean operators, they must be ALL CAPS: (( su ((sach ba) OR (sach bai)) me gioi bon thong minh ) OR ( vu sach che ve gioi vu hoang minh ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( su ((sach ba) OR (sach bai)) me gioi bon thong minh ) or ( vu sach che ve gioi vu hoang minh ))~".
• Adding a wildcard symbol may retrieve word variants: (( su ((sach ba) OR (sach bai)) me gioi bon thong minh ) or ( vu sach che ve gioi vu hoang minh ))*.
