• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y sang ((ma hoi) OR (xa hoi)). thien van nam duc va ((dinh lai) OR (dinh lap)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y sang ((ma hoi) or (xa hoi)). thien van nam duc va ((dinh lai) OR (dinh lap)) cua tre*".
