like

&facet.field={!ex=column1 !ex=column2}column1

however above is not working.

Answer 1

In the Solr wiki it says :

Both the tag and ex local params may specify multiple values by
separating them with commas.

So, it should be look like :

&facet.field={!ex=column1,column2}column1

I didn’t try it but think that it will work.
