> Add support for property existence query like
> {noformat}
> select [jcr:path] from [nt:base] where propa is not null
> {noformat}
> Opposite of this cannot be be supported i.e. {{propa is null}} though!
> With OAK-1208 query creation logic explicitly ignores such queries but with recent Lucene changes it appears to be possible LUCENE-995
