> I tried using {{DocBasedVersionConstraintsProcessorFactory}} on a field which
> was defined as :
> {code}
> <field name="myVersionField" type="long" indexed="false" stored="false"/>
> {code}
> The long fieldType has docValues enabled and since useDocValuesAsStored is
> true by default in the latest schema I can retrieve this field.
> But when I start Solr with this update processor I get the following error
> {code}
> Caused by: field myVersionField must be defined in schema, be stored, and be
> single valued.
> {code}
> Here's the following check in the update processor where the error originates
> from:
> {code}
> if (userVersionField == null || !userVersionField.stored() ||
> userVersionField.multiValued()) {
> throw new SolrException(SERVER_ERROR,
> "field " + versionField + " must be defined in schema, be stored,
> and be single valued.");
> }
> {code}
> We should improve the condition to also check if the field docValues is true
> and useDocValuesAsStored is true then don't throw this error.
> Hoss pointed out in an offline discussion that this issue could be there in
> other places in the codebase so keep this issue broad and not just tackle
> DocBasedVersionConstraintsProcessorFactory.
