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