• If you are trying to use Boolean operators, they must be ALL CAPS: (( toc sach ((ha ve) OR (ca ve)) gioi dong thong tin ) OR ( thu sach che va gioi bo trong kinh ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( toc sach ((ha ve) OR (ca ve)) gioi dong thong tin ) or ( thu sach che va gioi bo trong kinh ))~".
• Adding a wildcard symbol may retrieve word variants: (( toc sach ((ha ve) OR (ca ve)) gioi dong thong tin ) or ( thu sach che va gioi bo trong kinh ))*.
