I'm trying to build an index of lessons. In the Lessons-table I have a field for a previous and next lesson.
The problem is that I'd need to be able to index and make searches from those "previous lesson" and "next lesson" -fields also. But when I try to start up the server with @ManyToOne and @IndexedEmbedded -annotations in the
previousLesson I get a "Circular reference"-error. So I'd like to know how it is possible to index these referenced lessons also. I've tried searching the forum and Google, but I didn't find anything usefull. And this sounds kind of an easy problem so I thought someone could know answer for this straightly.
Thanks in advance!

</many-to-one>
Error:
