I believe that the collections have to have the same indexes. However, I
imagine that if you had one index built in each collection on Allfields, it
would work. But I don't think you can have indexes on metadata in one
collection that dosent exist in another collection for the supercollection
functionality to work properly.

Take a look at

- Bibliography
tiny collection of 10 bibliography entries illustrates the
*supercollection* facility which searches several collections
together, seamlessly. It operates together with the bibliography collection,
and its configuration file is almost the same.
