Description

Consider a query like

/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

And a seemingly non related index like

/oak:index/assetType
  ...
  - type = "lucene"
  + indexRules
    + nt:base
      + properties
        + assetType
          - propertyIndex = true
          - name = "assetType"

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
