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