Some experimental code for querying defined collecions and reindexing the collection-linked studies, so that
these non-owner, linked VDCs are indexed too. The current implementation pretty much brute-forces it; which
should be an interesting experiment on its own. (There are 2,000 collection in production; is this a lot? -
we'll find out shortly...) But if this approach proves viable, there are definitely ways to optimize the
whole thing.
