• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach nha ve gioi ro trong tin ) OR ( vu ((sach xa) OR (sach dao)) me gioi hon dong tin )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach nha ve gioi ro trong tin ) or ( vu ((sach xa) OR (sach dao)) me gioi hon dong tin ))".
