[bug#36390] [PATCH 0/3] Improve 'guix search' relevance and display

[Ludovic Courtès]

Hello Guix!

This improves ‘guix search’ in two ways:

  1. The relevance score now excludes things that do not match *all*
     the regexps.  So ‘guix search go game’ returns 28 results instead
     of 1,245 and the first one is ‘gnugo’; ‘guix search ssh client’
     returns 14 results instead of 510; ‘guix search guile crypto’
     returns just ‘guile-gcrypt’ instead of 279 results.

  2. ‘guix search’ and ‘guix system search’ now write at most a full
     screen of results.  You can pipe through a pager to view all the
     results.

Thoughts?

Ludo’.

  ui: 'relevance' considers regexps connected with a logical and.
  syscalls: Add 'terminal-rows'.
  ui: Add 'display-search-results' and use it.
