Hello,
I got an "Unexpected docvalues type SORTED_NUMERIC" exception when I perform group facet on an IntPointField. Debugging into the source code, the cause is that internally the docvalue type for PointField is "NUMERIC" (single value) or "SORTED_NUMERIC" (multi value), while the TermGroupFacetCollector class requires the facet field must have a "SORTED" or "SOTRTED_SET" docvalue type: https://github.com/apache/lucene-solr/blob/2480b74887eff01f729d62a57b415d772f947c91/lucene/grouping/src/java/org/apache/lucene/search/grouping/TermGroupFacetCollector.java#L313 When I change schema for all int field to TrieIntField, the group facet then work. Since internally the docvalue type for TrieField is SORTED (single value) or SORTED_SET (multi value). Regarding that the "TrieField" is depreciated in Solr7, can someone help on this grouping facet issue for PointField. I also commented this issue in SOLR-7495. Thanks.
