• To exclude log events that contain the ERROR term, and return all other log events, specify a filter pattern of "-ERROR".

• To return log events that contain the ERROR term, specify a filter pattern of "ERROR".

• To return log events that contain both the ERROR and Exception terms, specify a filter pattern of "ERROR Exception".

• To return log events that contain the ERRORor the Exception term, specify a filter pattern of "?ERROR ?Exception".
