How to set up and validate locally

1. Have a GitLab Premium license added
2. Visit https://3000-[...].ws-eu67.gitpod.io/admin/application_settings/advanced_search (or locally, Admin Area > Settings > Advanced Search)

Workaround if you don't have a GitLab Premium license:

diff --git a/ee/app/models/license.rb b/ee/app/models/license.rb
index 3c6a0b4d64a0..8b222f0d85a4 100644
--- a/ee/app/models/license.rb
