[PATCH] ui: Improve sort order when searching package names. |
|

Wed, 28 Sep 2022 11:27:37 +0200 |
Hi,
we provide a `guix serach`-based package search to our users and noticed
that searching for “ggplot2” yields the package r-ggplot2 on position
11 only – when it should be the first. Looking at other potential
search terms (haven, shiny, ape, renv, here, ini, setuptools) reveals
similar issues.
I propose we also score the unprefixed package name, so SCORE can award
bonus points for a full string match. I don’t like that we have to
maintain a list of common prefixes for this and that package names are
scored twice now, but I can’t think of a better solution right now.
Cheers,
Lars
* guix/ui.scm (%package-metrics): Increase score for PACKAGE-NAME and
add score for unprefixed package name.
