Hi,
I am trying to combine the mlt functionality with facets, but Solr throws
org.apache.solr.common.SolrException: ":"Unable to compute facet ranges, facet
context is not set".
What I am trying to do is quite simple, find similar documents using mlt and
group these using the facet parameter. When using mlt and facets separately
everything works fine, but not when combining the functionality.

In the above example I would like to facet on Journalnummer, thus grouping
several documents based on Journalnummer.
Hope someone can help me, and thanks in advance.
