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