(2) isn't viable. Updating a multiValued field is the same as any other field, a
delete followed by an add of the entire document.
(1) could work. The problem here is how you need to search. If you need
to search your notes it would be separate from the document. In other
words, you couldn't form a query like
"+body:(body text of interest) + notes:(stuff I put in my notes)
You could search for each independently, but not both together.
There's the "limited join" patch, see:
https://issues.apache.org/jira/browse/SOLR-2272
that hasn't been applied yet that *might* help. A variant of (1) is
that there's
really no need to have two separate cores. Documents in Solr don't need to all
have the same fields. So you could have, say, two types of documents,
"fulldoc" and "notesdoc". Fulldocs wouldn't have a "notes" field, and notesdocs
wouldn't have a "body" field. You'd have to take some care that the <uniqueKey>
was different for the two different types of documents. That might
work with 2272.
Warning: I haven't played with that patch, so caveat emptor.
