• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach lo nang xa hoi. ((hieu vu) OR (hieu su)) cham xuc va ((hanh van) OR (hanh va)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach lo nang xa hoi. ((hieu vu) OR (hieu su)) cham xuc va ((hanh van) or (hanh va)) cuu tre".
