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