• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty nang o hoi. lieu ((ha nam) or (((va nay) OR (va cay)))) xuat va thanh vinh cua triet~".
• Adding a wildcard symbol may retrieve word variants: tu sach ty nang o hoi. lieu ((ha nam) or (((va nay) OR (va cay)))) xuat va thanh vinh cua triet*.
