Great - that looks really nice. 

I tried some searches on a number of different files and they almost
all worked fine. However, when I tried searching Peter Seibel's
Practical Common Lisp PDF book (free download from Apress:
http://www.apress.com/free/index.html), there were mismatches between
the page that was displayed and the matching text. The page number
corresponded to the page number that was displayed; however, the
search term wasn't on the page. The line containing the match was
displayed correctly; however, it was for a page later in the
document. This seemed to happen for any searches I did of the PCL pdf
file.

First, I thought it might have something to do with the size of the
pdf file or blank pages not being counted; however, searches of the
sicp.pdf book all seemed to produce correct results, so I'm not sure
why the search functionality doesn't work properly in some instances.
