Search ebuild faster with eix

Problem :

You can search ebuild with emerge -s.Is there a faster way to search packet ?

Solution :

It exists a tool to make search faster on portage tree and other non official trees : eix

0) Install it :

  $ echo app-portage/eix >> /etc/portage/package.keywords
    $ emerge -av app-portage/eix

1) Update it (you have to do this after emerge --sync) : update-eix
2) Search a packet (for example mediawiki) : eix -s mediawiki
