Yes, indeed! Guess I have to do some more unlearning :)

But, I will for the time being use my current method of creating a  
design document for each field the user want this information for.  
Since users are now storing complex objects using my library, I want  
to avoid all the complex and often large data to be indexed. So they  
can now define for which fields the views are updated automatically...
