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