File indexer Nepomuk & Baloo (how to disable them)

Getting rid of those pesky file indexers will speed up your system a lot. Kubuntu 14.04 started to use Baloo. Unlike Nepomuk there is no option that disables it, but here is one way how to do it.
cd /usr/share/autostart
mv -i baloo_file.desktop baloo_file.desktop.not
mv -i nepomukbaloomigrator.desktop nepomukbaloomigrator.desktop.not
mv -i nepomukserver.desktop nepomukserver.desktop.not
Next time you boot the file indexer will be gone.
