guix package: '--search' sorts by relevance.
* guix/scripts/package.scm (find-packages-by-description): Rewrite to compute a score based on the number of regexps matched and the number of matches for each regexp. Sort according to this score and return it as a second value. (process-query) <'search>: Capture the two return values of 'find-packages-by-description'. Pass #:extra-fields to 'package->recutils'. * doc/guix.texi (Invoking guix package): Mention relevance, give an example.
