• If you are trying to use Boolean operators, they must be ALL CAPS: tu sai ky nang xa hoi. hieu va cam ((xuc van) OR (duc van)) hanh ((vi cua) OR (vai cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ky nang xa hoi. hieu va cam ((xuc van) or (duc van)) hanh ((vi cua) OR (vai cua)) tre".
