>
> 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:
> {code}
> //*[(((@jcr:primaryType = 'nt:unstructured')
> and (@resources = '/data' or @resolved = '/data'))
> or (@content = '/data' and (@jcr:primaryType = 'nt:folder'))) ]
> {code}
