> It would be good to have some stats exposed around property index specially for those based on ContentMirrorStoreStrategy
> The index structure is like
> {noformat}
> oak:index
>   + status
>     + :index
>       + PASS
>         + etc
>           + workflow
>             + instance
>               + a
>                 - match = true
>       + FAIL
>         + etc
>           + workflow
>             + instance
>               + b
>                 - match = true
> {noformat}
> # List of values being indexed - Like _FAIL_, _PASS_ etc or count
> # Path of content being index - Say path upto 3 levels where given property exists. For above case it would be _/etc/workflow/instance_
> #2 can be used to come up with right values for {{includedPaths}} OAK-3263. Having includedPath has benefits in terms of
> # Faster reindexing times
> # Make commits faster - Each property index currently contributes one {{IndexEditor}} and this editor would participate in *each* commit. If number of property indexes are high then it would lead to slow down in commit rates (OAK-1273). So having {{includedPath}} would allow reduction in number of editors that participate in a commit
