Thanks Shawn for your reply
I tried to bring the heap size to 5gb as you would like, but the problem 
was not solved.
"/If you have configured fts_solr with a URL that contains a # 
character, it's never going to work./"
I'm not sure how to configure this but in the 90-plugins.conf file I 
configured this:
plugin {
 ??#setting_name = value
 ??fts = solr
 ??fts_solr = url = http://5.39.2.59: 8987/solr/dovecot/
}
In the 10-mail.conf file I added this as a guide:
# Space separated list of plugins to load for all services. Plugins 
specific to
# IMAP, LDA, etc. are added to this list in their own .conf files.
mail_plugins = $ mail_plugins fts fts_solr
if I run one of these two commands as a guide
curl http://5.39.2.59:8987/solr/dovecot/update?optimize=true
curl http://5.39.2.59:8987/solr/dovecot/update?commit=true
I get
<? xml version = "1.0" encoding = "UTF-8"?>
<Response>
<lst name = "responseHeader">
 ??<int name = "status"> 0 </int>
 ??<int name = "QTime"> 2 </int>
</ Lst>
</ Response>
this is right? have I forgotten or am I wrong?
If you have time to see or try any queries, I have access to 
http://5.39.2.59:8987/solr/#/ without a password.
thanks for your time!
