Comment 26 for bug 1424815

I was able to determine it was specifically not working with 511(Casts) fields. I've amended my previous commit to cover 511 fields in the authors block. This has the unfortunate byproduct of including the (Cast) at the end of the field in the clickable link, though it isn't added to the actual search query, so as far as potential issues go, it's fairly benign.
