> Consider a query like 
> {noformat}
> /jcr:root//element(*, cq:Taggable)[ (@cq:tags = 'geometrixx-outdoors:activity/biking' or @cq:tags = '/etc/tags/geometrixx-outdoors/activity/biking') ] order by @jcr:score descending
> {noformat}
> And a seemingly non related index like
> {noformat}
> /oak:index/assetType
>   ...
>   - type = "lucene"
>   + indexRules
>     + nt:base
>       + properties
>         + assetType
>           - propertyIndex = true
>           - name = "assetType"
> {noformat}
> Then currently {{IndexPlanner}} would return a plan because even when it cannot evaluate any of property restrictions because it thinks it can sort on {{jcr:score}}. This later results in an exception like
> {noformat}
