• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky nang ((x hoi) OR (x ho)). hieu de nhan luc va thanh ((vi cua) OR (di cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky nang ((x hoi) or (x ho)). hieu de nhan luc va thanh ((vi cua) OR (di cua)) te".
