Apache Solr own grouping in autocomplete The apache solr autocomplete module don't work for me.
I try to achive a relative complex autocomplete,
my target is to achive this on the autocomplete:   

Search for "searchword":
-Facet for type/bundle
-Facets based on the results
Show all results for "searchword"  

As example:
Search for "test":
Download (176)
Systems (100)
News (20)
Services (5)
Systems
System 1
System n
Services
Service 1
Service n
Show all results for "test"  

Any suggestions how I could get this?

Edit: I use apache solr search for this so no search api hook here
(miss some functions in the search api based)
You can try to write your own query according to results you want to get.
