Question on "other language" than english stemmers and using both

[TG Servers <sr...@prvtmail.net>]

Hi,

I currently adapted this schema.xml for dovecot and Solr 7.2.1.
Now this is stemming only english words.
What do I have to do to use it for english AND german?
Can I just put the according german filterfactorys appended to it or
does that not work?
E.g.
...
<filter class="solr.KeywordMarkerFilterFactory" protected="protwords.txt"/>
<filter class="solr.EnglishMinimalStemFilterFactory"/>
<filter class="solr.GermanMinimalStemFilterFactory"/>
...

Thanks,
Thomas
