com.adobe.cq.dam.cfm.impl.search.ContentFragmentReferencePublisherProvider retrieves last modified date also from jcr:created

[kwin]

The com.adobe.cq.dam.cfm.impl.search.ContentFragmentReferencePublisherProvider has the following logic

Calendar determineLastModified(ContentFragmentReferencePublishProvider.ResourceType type, Resource resource) {
		ValueMap props = resource.getValueMap();
		switch (type) {
			case ASSET :
				return (Calendar) props.get("jcr:content/jcr:lastModified",
						props.get("jcr:created", Calendar.getInstance()));
			case PAGE :
				return (Calendar) props.get("jcr:content/cq:lastModified",
						props.get("jcr:content/jcr:lastModified", props.get("jcr:created", Calendar.getInstance())));
			default :
				return (Calendar) props.get("jcr:lastModified", props.get("jcr:created", Calendar.getInstance()));
		}
	}

I.e. there is a fallback from cq:lastModified to jcr:lastModified to jcr:created. The latter is auto-generated via mixin mix:created which is part of the node type cq:PageContent.

Supporting this either requires adding parametrization support if jcr:created is considered for a particular pattern and type or jcr:created can always be considered (although currently not true for all ReferenceProvider implementations).
