garrensmith opened a new pull request #1609: Mango match doc on co-ordinating node
URL: https://github.com/apache/couchdb/pull/1609
 
 
   ## Overview
   
   This fixes an issue when doing a rolling upgrade of a CouchDB cluster
   and adding commit a6bc72e the nodes that were not upgraded yet would
   send through all the docs in the index and those would be passed through
   to the user because the co-oridnator would assume it was matched at the
   node level. This adds in a check to see if it has been matched at the
   node level or not. And then performs a match if required.
   
   ## Testing recommendations
   
   This is tricky to test. If you have nodes running an older version of CouchDB, this should stop unmatched docs from being returned to the user.
