• The words AND, OR and NOT may confuse the search; try adding quotes: "((((hoc hieu) OR (doc hieu))) or (hoc hien)) manh - hanh trung cua nhung cong vinh toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((((hoc hieu) OR (doc hieu))) or (hoc hien)) manh - hanh trung cua nhung cong vinh toan ban*.
