Comment 1 for bug 1245944

My commentary on the proposed branch upon eyeballing it: using all of the subfields in the bib field to look up a matching authority record is an improvement over the status quo.

It's still not perfect, though: the order of subfields in the bib and authority headings are ignored, as is checking that the subject thesauri of the bib and authority heading match. Those concerns are long-standing, however, and reasonably the topic of a separate bug.
