I have not used that so can't comment. However, it looks like it is on top of IMAP or JMAP. I have >70K mails in my archive. Try that with IMAP and do a search and you will see what is wrong.
In comparison, LIV read mails directly off the maildir. It is basically the dumb down, web version of mu (https://www.djcbsoftware.nl/code/mu/), which LIV is based off.
Maybe my statement about other open source webmail is too provoking; but I think this is one of a new kind of webmail.

Wouldn't that entirely depend on the indexing used by the IMAP server? IMAP even supports full text searches with a single command.
Now if you are talking encrypted email, then, yes, IMAP is a problem for full text searches. But you can't do that server side using any method if the keys live only at the email client (as is proper).
Indexing is no longer optional, but necessary. And once you have that, IMAP just becomes an unnecessary intermediary. Why go through IMAP when you can read the mail directly from the underlying Maildir?
* If you just want to download some mails, there is the much simpler POP3
* If you want to access your mail remotely in a convenient way, there is webmail
* If you want to do scripting, or advanced manual operations on your mail store, there are terminal tools
IMAP can do all three but is a lousy substitute and holding you back.

That's exactly the point of having your own email server in the cloud with all your mails, so all of your devices can access the vast data through a common webmail interface, without downloading anything in advance.
