The connection between objects is key in our library domain though.

I've been contemplating how that would look and work. But the
downsides you mention are sorta show-stoppers for our needs:
The main one being query or facet by all tags for a specific user?
That's doable I think.
I assume an annotation is a comment (like a few sentences)?
If you search on comments, do you just get the comments back with a
pointer to the original doc, or do you get the original doc back?
Storing comments on a document:
- could lead to increased relevancy... all comments from all users would be
considered together for term-freq
- easy to get comments for a list of documents in a single query
- can use lucene syntax across "A" fields like tite, and commentary.
+title:solr+comments:great
- harder to search for comments from a specific user only
(need sloppy phrase or span queries to do this?)
Storing comments separately:
- if you search in comments, you get the exact comment that matched... if you
stored all comments on the A doc, you wouldn't know which matched
(but highlighting
could help with that).
- easy to search comments only from a specific user
Do comments need to be included in faceting in any way?

rather fuzzy headed :-)
