> The node name queries don't use any index currently, making them really slow and triggering a lot of traversal warnings.
> Simply adding node names to a property index would be too much content indexed, but as Lucene already indexes the node names, using this index would be one viable option.
> {code}
> /jcr:root//*[fn:name() = 'jcr:content']
> /jcr:root//*[jcr:like(fn:name(), 'jcr:con%')] 
> {code}
