Queries are not being sent to solr when search on server issued via imap client.

I found the problem. "mail_plugins = fts fts_solr" has to be set within "protocol imap" as well.

When I issue "doveadm search box <string>", I can see the search string in the output of tcpdump and also in the solr logs. Solr seems to have been initialized correctly, in that when I issue a query via curl, I receive the correct results.
