Tosca > TDM TQL search within a search

In our repository we have a TDM structure where the different TDM objects are linked with reletions. If you want to find one property via its link with another property this is done via a TQL query:

->RETURN All:[TDMObject1]->[TDMObject2][Property=="[property_value]"]

or: in human readable:

-> RETURN All:Portfolio->Client[Username=="login01"]
