• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ty) OR (sach thu)) ang xa hoi. thien van cac xuc van ((dinh vai) OR (dinh van)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ty) OR (sach thu)) ang xa hoi. thien van cac xuc van ((dinh vai) or (dinh van)) cua te".
