I have a list of synoynms which is being expanded at query time. This yields
a lot of results (in millions). My use-case is name search.

I want to sort the results by Levenstein Distance. I know this can be done
with strdist function. But sorting being inefficient and Solr function
adding to its woes kills the performance. I want the results to be returned
as quickly as possible. 

One of the ways which I think Levenstein can work is, applying the strdist
on the synonym file and getting the scores of each of the synonym. And then
use these scores to boost the results appropriately, it should be equivalent
to levenstein distance. But I am not sure how to do this in Solr or infact
if Solr supports this.
