One feature I'd like to be able to see is the ability to search pages  
for a fragment of (Daisy) HTML.

I apologies if this is already possible, I have tried to find such a  
feature in the past but was not successful. It seems (to me) that  
Lucene only indexes the rendered text not the HTML code(?).

My current work around is to search directly against the repo server  
blobstore directory.
