• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc hieu) OR (doc hieu)) manh - canh doanh ((cua khong) OR (cua thuong)) cong dan phan tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc hieu) or (doc hieu)) manh - canh doanh ((cua khong) OR (cua thuong)) cong dan phan tu".
• Adding a wildcard symbol may retrieve word variants: ((hoc hieu) or (doc hieu)) manh - canh doanh ((cua khong) OR (cua thuong)) cong dan phan tu*.
