> The following XPath query is converted to a union, however there is still an "or" in the converted query, which means the query still can't use all indexes and has to traverse the whole repository:
> {noformat}
> /jcr:root/a/b//element(*, nt:unstructured)[(
> (@sling:resourceType = 'x' 
> or @sling:resourceType = 'dam/collection') 
> or @sling:resourceSuperType = 'dam/collection')] 
> {noformat}
