• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach thue dang xay hoi. hieu van chao xu ((van thanh) OR (van tuan)) vi cua triet~".
• Adding a wildcard symbol may retrieve word variants: thu sach thue dang xay hoi. hieu van chao xu ((van thanh) OR (van tuan)) vi cua triet*.
