• The words AND, OR and NOT may confuse the search; try adding quotes: "bo sach ty nang xa hoi. hieu hien ((thanh thuoc) OR (hanh thuoc)) va xanh tai cua tu~".
• Adding a wildcard symbol may retrieve word variants: bo sach ty nang xa hoi. hieu hien ((thanh thuoc) OR (hanh thuoc)) va xanh tai cua tu*.
