<br>
Just a status update, in case this can help others.
<br>
<br>
We went forward and disabled the position information indexing and
the re-indexed of our mail data (over a couple of days to avoid
overloading the systems). Before the re-indexing we had 1.33 TiB
in our Solr Indexes. After re-indexation, we had only 542 GiB,
that's a 60% of our storage requirements for our FTS indexes :)
<br>

this optimization also produce a less RAM requirements on Solr
server?<br>

So far, we haven't been reported any issue or measurable
differences by our users concerning the quality of the FTS. From
further debugging, as discussed on the solr-user mailing list
(<a class="moz-txt-link-freetext" href="https://lists.apache.org/thread.html/rcdf8bb97be0839e57928ad5fa34501ec8a73392c11248db91206bc33%40%3Cusers.solr.apache.org%3E">https://lists.apache.org/thread.html/rcdf8bb97be0839e57928ad5fa34501ec8a73392c11248db91206bc33%40%3Cusers.solr.apache.org%3E</a>),
I've come to the conclusion that, with the current integration
between Dovecot and Solr (esp the fact that `"` is escaped), it's
impossible to trigger phrase queries from user queries as long as
autoGeneratePhraseQueries is false.
<br>
<br>
I've attached the schema.xml and solrconfig.xml we are now using
with Solr 8.6.0, in case there is any interest from others. Let me
know if you prefer a MR to update the xmls present in

<p>The attached schema and config file also works with Solr 7.7.0?
Since dovecot provide schema and config for 7.7.0 will be useful
for many of us a path based on it.</p>
<p>Thanks<br>
