Exactly. With MarkLogic, a server-based indexed repository from the
company where I work (marklogic.com), you could execute a query like
that in roughly a second, once the document was loaded and indexed. In
fact, functionality exactly like what you're trying to do is used by
large medical journal aggregator customers of ours to display citation
counts of articles, for example.
Without an indexed repo, I think you're going to have a hard time.
