How to search on emacs-devel?

[dalanicolai]

Is there any (other) guide about how to search in the emacs-devel archives?

I am frequently trying to find some old threads, and the search functionality usually seems to be of

no help. As the bottom of the archives page (https://lists.gnu.org/archive/html/emacs-devel/) tells

me that the search functionality is powered by `Namazu`, I have tried to find in its docs how to use

it. It says that using a space in a query, by default, does the same as the AND operator (see

http://www.namazu.org/doc/manual.html#query). However, when testing it, I have found that that is

not the case (also the and operator does not work).

Wouldn't it be a good idea to add some info about how to use the search functionality?
