You have the option to search for all work items written by a particular rapporteur. You may type a first name, last name, a part of a name using * as a wildcard or just click on 'LIST' to get a list of all rapporteurs.

Secondly you have the option to search by the organisation of the rapporteur. You can be specific by typing for example, 'ALCATEL BELL' or if you only know that the rapporteur works for ALCATEL but you are not sure which subsidiary then type ALCATEL* and you will be given a list of all work items under the responsibility of any rapporteur working for any subsidiary of ALCATEL.
