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