Yep. The basic approach ZOE takes is to create one index per class and index the primary and foreigns key as keywords. It then query the different indexes to simulate a "relational" storage... Which is all handy, dandy... On the other hand, if you already have a relational database in the first place, there is no reason to go through this circus in the first place...

  You may want to look at its source.

If you are so inclined, you can check the alt.dev.szobject package for more gory details. In particular, SZIndex deals with Lucene directly.

You can find the app and its source here:
