• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ty) OR (sach y)) nang xa hoi. hieu va cao duc va thanh va ((chua te) OR (chua xe))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ty) or (sach y)) nang xa hoi. hieu va cao duc va thanh va ((chua te) OR (chua xe))*".
