Adrien Grand commented on LUCENE-10468:
---------------------------------------

I agree that there is inconsistency between doc-values-based queries, which 
would fail if the field is not indexed with the right doc-value-type, and 
term-based queries, which would leniently return no match when used against a 
field that e.g. only indexes doc values. But if we want to change one, I'd 
rather change term-based queries to be less lenient. I can't think of a single 
case when this leniency would be desired? It makes total sense to me to return 
empty results when the field does *not* exist. But if it exists and is not 
indexed correctly, it's better to fail?

> 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'?
