Hello again, We found another oddity when upgrading to Solr 8. For a *:* query, the facet counts for a simple string field do not match at all between these versions. Solr 7.7.1 gives less or zero counts where as for 8 we see the correct counts. So something seems fixed for a bug that i was not aware of, although are unit tests rely heavily on correct facet counts.
When i do a field query <field>:<facet_key> the numFound matches the correct facet counts i see on Solr 8. I checked CHANGES.txt for anything on this subject, but the issues do not seem to match this description. Does anyone have an idea what difference in behaviour i see, and what ticket dealt with this subject? We do not use JSON-facets here. Many thanks, Markus
