group.facet fails when facet on double field
Hi,
We are trying to upgrade from Solr 4.8 to Solr 6.2.
This query:
?q=*%3A*&start=0&rows=2&wt=json&indent=true&group=true&group.field=mediaObjectId&facet=true&facet.field=rating&group.facet=true
is returning the following error:
null:org.apache.solr.common.SolrException: Exception during facet.field: rating
at org.apache.solr.request.SimpleFacets.lambda$getFacetFieldCounts$0(SimpleFacets.java:739)
at java.util.concurrent.FutureTask.run(FutureTask.java:266)
at org.apache.solr.request.SimpleFacets$2.execute(SimpleFacets.java:672)
...
Caused by: java.lang.IllegalStateException: unexpected docvalues type
NUMERIC for field 'mediaObjectId' (expected=SORTED). Re-index with
correct docvalues type.
at org.apache.lucene.index.DocValues.checkField(DocValues.java:212)
at org.apache.lucene.index.DocValues.getSorted(DocValues.java:264)
at org.apache.lucene.search.grouping.term.TermGroupFacetCollector$SV.doSetNextReader(TermGroupFacetCollector.java:128)
...
The same query without the group.facet=true option does not give an
error. On Solr 4.8 the query did not give problems.
The relevant fields are configured as follows:
<fieldType name="double" class="solr.TrieDoubleField"
precisionStep="0" positionIncrementGap="0"/><field name="rating"
type="double" indexed="true" stored="true" multiValued="false"
/><field name="mediaObjectId" type="long" indexed="true" stored="true"
multiValued="false" />
Am I doing anything wrong, or do you have any suggestions on what to try next?
Best regards
Karel Braeckman

Thanks for your reply. I don't think this is what is causing the error
though.
We are starting from an empty index and have fully re-indexed a couple of
documents. The query is still failing with the same error.

This error is thrown when you add (or remove) on an existing field but do
not reindex you data from scratch. It is result of removing field cache
from Lucene. Although you were not getting error with Solr 4.8, I am pretty
sure that you were getting incorrect results.
Stand up a small test cluster with Solr 6.2.X and index a few documents in
it and try your group.facet query, it would definitely work.
