Search for hypermail?

Question

Email

Good afternoon.
I took care of adding a search for mail archives in hypermail. They recommend Xapian, but the documentation section is there now, for example, hanging ( xapian.org/docs ), well, in general, I would like something ready.
Google didn't help much, surprisingly.
Click, please.
Alternatively, suggest an analogue of hypermail with built-in search. Requirement: correct work with mbox and attachments.
E: Documentation no longer hangs, but the question is still relevant.
