Hi everybody, Why it is possible to define an index over several attributes (and
the file is ordered taking all of them into account, in the order
these attributes are specified), but it is only possible to define a
cluster over a single attribute?

Hi everybody,
I have some doubts about these topics. I hope you can help me:
- I have read that some queries can be solved by just querying the indexes, without actually retrieving data. I don't see this point.
