• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((y nang) OR (v nang)) xa hoi. hieu van cham soc va danh dai ((cua dieu) OR (cua vat))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y nang) OR (v nang)) xa hoi. hieu van cham soc va danh dai ((cua dieu) or (cua vat))*".
