Both Roundcube and Squirrelmail webmail cannot search for anything + cannot open many emails because there are more than 200, 000 emails in my Inbox

[Turritopsis Dohrnii Teo En Ming]

Dear Shawn Heisey,

My Dovecot, Postfix, Roundcube and Squirrelmail were automatically
installed, configured and deployed by Virtualmin web hosting control
panel install scripts.

How do I integrate Apache SOLR searching capability with Dovecot? Are
there any excellent guides for this?

Thank you.
