• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty nang xa hoi. hieu ve cam tuc va ((thanh pho) OR (((hanh lam) OR (thanh lap)))) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty nang xa hoi. hieu ve cam tuc va ((thanh pho) or (((hanh lam) OR (thanh lap)))) cua tre".
