This Solr instance is not configured properly for dovecot.  Most of the 
fields are configured as multiValued (which is why you see an array 
rather than a single value), and the response is JSON.  A Solr instance 
that is properly configured for dovecot would return XML, not JSON.

You're going to want to provide a proper solrconfig.xml and 
managed-schema file, restart Solr or reload the core for dovecot, and do 
a full reindex.  At the following URL, you can find the shell script 
that I use to do a full reindex:

At the following URL are links to the solrconfig.xml and schema that are 
appropriate for dovecot.  These instructions say to name the schema file 
"schema.xml" ... this will work, as long as Solr has read-write access 
to the conf directory so it can rename the file to "managed-schema".  If 
it doesn't, then you should name the file "managed-schema" yourself.
