I didn't know about that, but would be awesome. Let's find out if it's really possible. Marc, do you happen to remember / have a link?

All my remarks on this subject basically aim to eliminate or reduce the full reindexing of an object after an indexed field on it changes. Because some class hierarchies can be quite extensive @IndexedEmbedded can generate a large amount of queries, especially with LAZY connections. I believe when I created this issue I had read something about Numeric fields being updateable in Lucene 4.

@Marc Schipperheyn, what do you have in mind here and what do you mean with "eliminating cascading object tree initialization."?
