"Any project" filter in search doesn't find results

In GitLab Community Edition 8.2.2 when I use the search bar, the default behaviour is to filter the search on "any group" and "any project".

This first search won't return any results. However if I change the project filter to a project I know the searched word exists, it will return results.

I would expect "Any project" to return results as specific projects do.
