search problem dovecot 2.2.21 + fts - Solr

[Anderson Barbosa]

Hello,

Realized update dovecot on my server. Now the search is returning
differently from the previous version bringing reference information of
other messages .
For example when doing a search for anderson.joao this new version of the
dovecot dovecot 2.2.21 + fts - Solr response will be all email that has the
word anderson and joao, instead of returning only items with the word
anderson.joao.

Before used version 2.2.18 + dovecot fts - Solr and the problem did not
occur .
For example practical test :

Dovecot 2.2.18

Even using characters Special "" \ scape, ' ' for an answer will always be
all emails with the word anderson and joao.
Checking the Changelog dovecot noticed que NAS versions Previous v2.2.20
and v2.2.19 certain changes with respect to fts .

There Have Another way to Make Search for Exact Word In this new version to
loft?
