Apache Solr and complex data architecture

At the moment I'm working on a highly relational content architecture and the related Solr backend. It's quite special from the practical use case point of view. In a nutshell it's a huge logical monster content that is separated to over several content types and referenced fields so we can maintain the most optimal normal form.

Information flow

When I was a kid we had this book about electricity. There was a tutorial how to create a small engine using paperclips and battery. I couldn't do it but I was fascinated how can you create a more complex thing from something basic. (I know it's not entirely true.) For many years I thought making complex things what really motivates me. Then I realized it's information that is amazing.
