You must configure your lookup service into the process flow run by the iEI listener. Any stored attributes are made available to the actual lookup as special registers in the name space iei. For example, if you can recover the indexed record by the simple SQL select statement "select * from database where key=<value>" and you have stored the <value> as look=<value> at the time of the index, then you might configure the standard iWay SQL Service to substitute sreg(ibi.look) into the SQL statement.
