Is there a possibilty to query the https://alm.example.com/qm/oslc_config/resources/com.ibm.team.vvc.Configuration by projectArea?

Firstly, I hope you are not hard coding that URI. It looks like that endpoint URI is for an OSLC query capability. In which case, you should be using OSLC Discovery through an OSLC Service Provider Catalog to find the OLSC service providers and any OSLC Query Capabilities they support for specified types of resources.

See https://docs.oasis-open-projects.org/oslc-op/core/v3.0/os/discovery.html for details.

    oslc:queryCapability  [ a                   oslc:QueryCapability ;
                            oslc:queryBase      <https://localhost:9443/qm/oslc_config/resources/com.ibm.team.vvc.Configuration> ;
                            oslc:resourceShape  <https://localhost:9443/qm/oslc_config/resourceShapes/com.ibm.team.vvc.Configuration> ;
                            oslc:resourceType   <http://open-services.net/ns/config#Configuration> ;
                            dcterms:title       "Default query capability for Configuration"^^rdf:XMLLiteral
                           ] ;

To query for specific properties, you use an oslc.where parameter.
See https://docs.oasis-open-projects.org/oslc-op/query/v3.0/os/oslc-query.html#oslc.where

However, when I tried a query on process:projectArea is (after using a oslc.prefix parameter to define the process namespace), it reported the error:

AQXCM5004E The query, process:projectArea, is invalid.    

        

So it appears that the query capability does not support querying on that property.

I also noticed and submitted an ETM defect. The resource shape referenced in the declaration of the query capability should describe the shape of the Query Result Container (see https://docs.oasis-open-projects.org/oslc-op/query/v3.0/os/oslc-query.html#query-result-containers), not the shape of its members. ETM is not doing that. That shape should then include a property for the member property that includes an oslc:valueShape that references the shape of the members. The resource shape ETM publishes does not describe the process:projectArea property, so this suggests that the property cannot be queried on, confirmed by the above error message.

So the short answer to your question is that it appears your use case is currently not supported. You will have to post-process the query results to exclude configurations that are from project areas that are not of interest.

If you look into the where syntax, you will note that the argument right to the equals always is enclosed with ". Also read up on and note that the Query part of the URI has to be URL encoded. I do not know at the moment if you can pass the UUID of a project area as parameter.
