Searching with * in site shows "unexpected" results

1. Run http://www.demo.test.onehippo.com/
2. In search field type star and click enter
3. Below result is shown
http://www.demo.test.onehippo.com/search?query=*

Issue - On the right hand side, in facet navigation I see below three items which are not expected. (refer attachment)
• hippostd:directory (2)
• hippogogreen:restapi (2)
• ef:form (1)

Also the fix should take care the "ordering" as well, currently it is ordered based on occurrences in a category - As per Arje it should be ordered "alphabetically".
Note - Talk to Arje before implementation.
