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