> Consider a content like
> {noformat}
> + /test
>    - foo=bar
> {noformat}
> with index def faceting multiple properties - something like
> {noformat}
> + /oak:index/foo/indexRules/nt:base/properties
>    + foo
>       - propertyIndex=true
>       - facets = true
>     + bar
>       - facets = true
> {noformat}
> Then a  query like
> {noformat}
> SELECT [rep:facet(foo)], [rep:facete(bar)] FROM [nt:base]
> {noformat}
> should not fail.
> Note that the failure requires requesting on multiple facets and one of them must not have any indexed value.
