• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach cha le gioi phap khong minh ) OR ( te sach ha ((me giai) OR (de giai)) san thong tin )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach cha le gioi phap khong minh ) or ( te sach ha ((me giai) OR (de giai)) san thong tin ))".
• Adding a wildcard symbol may retrieve word variants: (( tu sach cha le gioi phap khong minh ) or ( te sach ha ((me giai) OR (de giai)) san thong tin ))*.
