Indeed.

I really appreciate your messages. Maybe I have another question or idea in
my mind which aims in the same direction:
Why do I have to tell the DBMS which fields to index?

The DBMS can manage this by monitoring the accesses to attributes, maintain
this information and build an index itself.
