• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ly nang xa hoi. hieu va cac thuc giai ((thanh vi) OR (thanh va)) ((cuu tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ly nang xa hoi. hieu va cac thuc giai ((thanh vi) OR (thanh va)) ((cuu tre) or (cua triet))".
