• If you are trying to use Boolean operators, they must be ALL CAPS: (( te ((sach cha) OR (sach nha)) ve gioi lap truong ton ) OR ( te sach xa ke giai con hong tin ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te ((sach cha) OR (sach nha)) ve gioi lap truong ton ) or ( te sach xa ke giai con hong tin ))~".
• Adding a wildcard symbol may retrieve word variants: (( te ((sach cha) OR (sach nha)) ve gioi lap truong ton ) or ( te sach xa ke giai con hong tin ))*.
