• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang xa hoi. lieu va cham ((tuc va) OR (thuc va)) ((thanh vi) OR (hanh vi)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang xa hoi. lieu va cham ((tuc va) OR (thuc va)) ((thanh vi) or (hanh vi)) cua tre".
• Adding a wildcard symbol may retrieve word variants: su sach ky nang xa hoi. lieu va cham ((tuc va) OR (thuc va)) ((thanh vi) or (hanh vi)) cua tre*.
