• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach ty nang xa hoi. hieu ((ve cham) OR (vu cham)) doc va thanh dai ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ty nang xa hoi. hieu ((ve cham) or (vu cham)) doc va thanh dai ((cua tre) OR (cuu tre))*".
