Solr works best if all the data for an individual document is contained
in a single flat schema.  As soon as you try to put some of the data in
one index and some of the data in another index, you'll probably run
into problems combining the data and/or problems with performance.  Solr
does have some join capability, but when it is mentioned, usually it is
to discuss the things it CAN'T do, not the things that it can do.

What kind of security requirement would necessitate splitting data that
logically belongs together?
