• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hieu lang) or (((chieu sang) OR (nhieu tang)))) - hanh trung cua ban cong tran thanh cap~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hieu lang) or (((chieu sang) OR (nhieu tang)))) - hanh trung cua ban cong tran thanh cap*.
