• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty sang tay hoi. hieu vu cham soc ((ban hanh) OR (va danh)) ((lai cua) OR (lai chau)) te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty sang tay hoi. hieu vu cham soc ((ban hanh) or (va danh)) ((lai cua) OR (lai chau)) te~".
