I think the rub is that you need to take your results and explicitly add them to a concern *as well as* to the concern space: 

    //create a concern
    Concern vClasses = new ConcernImpl("vClasses",
        IntensionalOrExtensionalGroup.GroupKind.INTENSIONAL, _space);
    Pattern query = new PantherPatternImpl("class V*");
    vClasses.setSpecificationDefinition(query);
    //add it to the space
    vClasses.addToContextForIntensionalSpecificationEvaluation(_space);
    vClasses.evaluate(new UninterruptibleMonitor());
If I'm right, then having done this you can limit the scope of a query to your concern like this: 

    QueryContext context = new QueryContextImpl();
    context.setInputCollection(_space);

    Pattern allCallsinVClasses = new PantherPatternImpl("in(concern vClasses)
        && call ( * *(..))");
    context.setQuery(allCallsinVClasses);
    Searchable result = context.evaluateQuery(new UninterruptibleMonitor());


Let me know if this helps...  I'm just trying to figure this all out myself!

Hi all,
I have been trying to explore the programmatic support of CME. I went through the sample project given in the CME demos folder, as given there 
to run a query on the input concern model we do
something like this



// Indicate that the colleciton to be searched is to be the entire


concern space.


	context.setInputCollection(_space);
	  // Set up the query itself, in the Panther query language.
		Pattern query = new PantherPatternImpl("class V*");
		context.setQuery(query);




  	// Execute the query.
	SearchableRead result = context.evaluateQuery(new


UninterruptibleMonitor());


           Now if I want to filter out the query results further, for
example running the
query "call ( * *(..))" on the query results obtained earlier how do I
do it?  I tried setting
the query context's input collection to hold the query result,  but
doing so would detach
the  original universal concern space, and is not giving me any results.


    What I am trying to do programatically is equivalent to running a
query  like "class V*"
and then adding all the obtained results to a new concern and then running a query like "call( * *(..))" on this concern. 

   Any help on this will be greatly appreciated.

Thanks and Regards
Santhosh.
