Yes. I see it.
Why it’s dosen’t work for this query “urs meister Service public”?

Try to query your Solr index with:

?q=text:urs meister Service public

?q=text:urs meister

?q=text:Service public

Work only for this
?q=text:Service public

Did you query your index directly ?

Work only for this

no. THey are return many results. But there is no

It’s working if i am using this “urs meister den Service public”.
But not working for this “urs meister Service public”.
The problem in one word. It’s possible to use some settings to get it work with “urs meister Service public”?
