This might exist?
How about a list of index listeners that is called when an index is
updated? I want it to clear my hits cache. Perhaps it could be
interesting for other people to know what document was changed.

Lucene itself doesn't provide this, but Solr does. And with Solr you
don't need your own custom Hits cache - it already provides caches in
several areas.

I'm not using Solr :) But what you suggest is that I should try to fit
in in my own layer around Lucene rather than in Lucene?
May I ask why?
Not sure if I would do it that way. To me it

I guess that would be whenever an IndexReader that had new deletions
is closed, or an IndexWriter that changed the segments file?

The persistence mechanism.
So that would be a part of the the current Lucene API.

I don't really get what the point of such a low level callback mechanism
would be ... do you have uses cases where you're really going to want to
know every time someone uses a Directory object to do something

I mostly look for the Solr-kind-of-solution for now, but I will
absolutely keep my mind set on that the layer should allow hooks deep in
the code.
