   One last comment - you mention purging. Do you mean use of the actual 
`/{db}/_purge` endpoint, or just document deletion? As the warning in the 
documentation states, this is an endpoint of last resort. It's possible that 
use of `/{db}/_purge` for anything other than the occasional deletion may have 
introduced corruption -- this is a usage scenario the CouchDB team doesn't 
support.
   
   > [Purging a 
document](http://docs.couchdb.org/en/1.6.1/api/database/misc.html?highlight=purge)
 from a database should only be done as a last resort when sensitive 
information has been introduced inadvertently into a database. In clustered or 
replicated environments it is very difficult to guarantee that a particular 
purged document has been removed from all replicas. Do not rely on this API as 
a way of doing secure deletion.
