• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((hieu nganh) OR (hieu manh)) - hanh trong ung dung cong san ((toan cau) OR (toan cao)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((hieu nganh) or (hieu manh)) - hanh trong ung dung cong san ((toan cau) OR (toan cao))".
