Fig. 4.7 The setting of the distributed enterprise search platform applied in the pilot project with
three different broker agents contacted by the client
Figure 4.7 visualizes an employee in their working environment. When trigger-
ing a search, the search client on the employee's desktop communicates with three
different so-called broker agents. Each broker agent represents different repositories
that the employee has access to. See Sect. 4.3.1 for details about these reposito-
ries. Each broker agent is responsible for a group of multiple repositories contain-
ing disjoint indices. Before accessing the indices of the individual repositories, the
employee's credentials are submitted to guarantee access in accordance to the com-
pany's requirements. In the remainder of this section, we introduce the separated
network areas in detail. Section 4.5.1 describes how the city administration's meta
directory and internal websites are indexed and made available for all employees of
the city. Section 4.5.2 describes how the system is used to access files and information
that are stored in the internal repositories of individual government branches. Index-
ing and retrieval of local files, i.e., files that are stored on the employee's desktop
computer is presented in Sect. 4.5.3 . The graphical user interface of the system is
described in Sect. 4.5.4 .
