I artificially created a situation like this in my mailbox.  I created a 
new folder and copied all my other messages in my mailbox to it in the 
Linux commandline.  Ended up with 154K messages in that folder.  Then I 
had to force a complete reindex. Which I have a script for.

I'm using Solr for dovecot searching.  If you do something similar and 
have dovecot connect to something external for search, that should solve 
the first problem.

The folder did eventually populate in roundcube, though it did take a 
while.  My roundcube version is 1.5.2, and my dovecot version is 
2:2.3.18-4+ubuntu20.04.  Dovecot is installed from the official project 
APT repository on Ubuntu Server 20.04.

I seem to be having a problem with my Solr search engine.  No matter 
what keyword I search for in that folder, it always gets 127168 hits.  
That is just not possible when searching for "dragon" and then "aardvark".

Thanks,
