• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) ty nang xa hoi. hieu qua cac xuc va hanh ((vi cua) OR (vai cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (vu sach)) ty nang xa hoi. hieu qua cac xuc va hanh ((vi cua) or (vai cua)) tre*".
