Hi Guix, I’ve just updated mumi on issues.guix.gnu.org. The new version is quite a bit faster and features a more accurate search.
This is accomplished by storing essential bug information (such as submitter, owner, status, and tags) locally in a sqlite database in addition to indexing all original emails that are downloaded from Debbugs. The search no longer issues a complicated request to Debbugs. Instead it is performed on the local message index, and any filtering based on information not contained in the email messages (like submitter, owner, status, and tags) is perfomed using the sqlite database. This is not perfect and a few slow Debbugs operations still remain, but in general issues.guix.gnu.org should be much more usable now. The code is here and I appreciate patches to improve it: https://git.elephly.net/software/mumi.git -- Ricardo
