• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty sang tao hoi. hieu vu cham soc ((va hanh) OR (va dinh)) ((lai cua) OR (lai chau)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty sang tao hoi. hieu vu cham soc ((va hanh) or (va dinh)) ((lai cua) OR (lai chau)) tre~".
• Adding a wildcard symbol may retrieve word variants: tu sach ty sang tao hoi. hieu vu cham soc ((va hanh) or (va dinh)) ((lai cua) OR (lai chau)) tre*.
