Comment 3 for bug 1790231

Thanks for this patch, Jeff, and for the testing, Garry. The only problem I see is with the genre heading links. Those are in a slightly different format (they're written as facets), which don't need and don't play well with contains=>'exact'. With your patch applied, clicking on any genre heading link returns 0 results. I'm adding the needsrepatch tag for this reason.

For your testing pleasure, by the way, here are the IDs of the 21 records in the concerto dataset that include genre headings:
