• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (tu sach)) ky sang ma hoi. hieu su chao ((xu gia) OR (xu giao)) thanh vi cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) OR (tu sach)) ky sang ma hoi. hieu su chao ((xu gia) or (xu giao)) thanh vi cua tu".
