The test suite consists of a simple client that sends a CQL query to 
a search system service and gets back a gRS2 endpoint reference.

There are 5 steps in order to use this client:

1) Place the stubs of the search system service in your CLASSPATH
2) Configure the contants SEARCHURI, QUERY inside the Client. The 
first one is the search service EPR and the second is the string for 
the CQL query.
3) In the CQL query you must specify the fieldIds instead of the 
fieldNames(e.g. "79697524-e3bf-457b-891a-faa3a9b0385f contains image" 
instead of "title contains image"). The name-id mappings can be monitored 
through the SearchManagerPortlet:

4) Compile the Client.java
5) Run the Client and get back a gRS2 epr. Use then a client for reading 
this result set, and viewing the results.
