The problem is that I can't easily create the new record. There is some 
data that I no longer have access to, but did at the time I created the 
record to begin with.

This is what I'd like to know how to do. I'll experiment with this, but 
I thought that I wouldn't be able to get back all the info I need to 
recreate the doc.

I would like to get the record from solr because I just can't create the 
record the same way as I originally did.

(Besides the time involved in crawling all those websites, some of them 
only allow us access for a limited amount of time, so to reindex, we 
need to call them up and schedule a time for them to whitelist us.)
