Solr stats facet left out some values

I want to facet over products in Solr and want to retrieve statistics about the categories. My schema has got a field called categories, a multiValued field. the problem is, that the statistics left out a bunch of categories. Am I wrong with following query? Obviously, but how do I make it right? Pleeeease help, I'm despairing.

q=*:*&rows=0&stats=true&stats.field=product_id&rows=0&stats.facet=categories
Solution

  • The query looks fine, the problem is that it's faceting on a multiValued field:

    Computing statistics using stats.facet over a multi-valued field does not work properly.

    Hope this helps!
