Adrien Grand commented on LUCENE-10468:
---------------------------------------
This looks like a feature to me, not a bug. If you are getting this error
message, it means that you expected this field to be indexed with doc values
but in fact it wasn't?
> Do not always do checkField() in DocValues.getXXX(LeafReader, String)

> IndexQuery can always get an empty result when field in Query does not exist
> or even it was indexed with different FieldType.
> But when doing DocValuesQuery and field in such query does not exist, if this
> field was not indexed by any other FieldType, DocValues query's behavior is
> as the same as IndexQuery, otherwise it will throw a exception, because
> getting a DocValuesIterator always do DocValues#checkField(...).
> I mean checkFIeld(...) is not needed if only do getting a DocValuesIterator,
> and the exception's content is not friendly, so we can keep 'query result
> consistency'?
