"Reviews by work" is pulling in works from categories other than reviews

[kmcmullen]

On the index page for contemporary reviews of Chesnutt, we offer an option to "find reviews for specific Chesnutt works," however, when you go to that page, you find links to items that are not reviews. I think this is because it is only looking for keywords in the for "works", regardless of whether the file is a review or not. I'm not sure if there's a way to limit the items that show up on this page to reviews (it would just be a matter of only grabbing things with a keyword n="subcategory" of "Reviews")

For example, go here and click on the second result ("Inside View of the Negro Question"), which takes you to a piece of correspondence that lists that work. Same if you click on "A Roman Antique" a few lines further down.
