• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu sang) OR (chieu sang)) - hanh tranh cua dung cong san ((than cap) or (khan cap))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu sang) OR (chieu sang)) - hanh tranh cua dung cong san ((than cap) or (khan cap))*.
