I think this is some kind of parsing bug from the response from solr.
The number of pairs of errors returned is the same number of hits
received during the search. So if I do a search with 7 results turned
up, I get 7 pairs of errors.
Fixed with the following:
1) simplified config file by removing the "fts_encforce = no" from
90-plugin.conf
2) blew away the manages_schema file on the solr server
3) reloaded solr data store
4) deleted the solr index for the data store
5) rescanned the emails with doveadm
No more errors.
