bug#35551: guix search

[znavko]

Thank you, Ludovic. It will be nice to have some additional fields computed 
with Internet databases like:

Tag->name
Tag->Relevance
Purpose: editor, viewer, library, development tool
Interface: gui app, console-only, console and gui, system calls

For every tag needs to determine relevance.
For example, package VLC:
Tag->name: video
Tag->relevance: 100
Tag->name: view
Tag->relevance: 90
and other tags
Purpose: viewer
Interface: gui app

This can give additional options for search or just improve sorting when user 
type f.e. ' guix search video viewer'
