Intent to backport OAK-6750 and OAK-6792 to 1.6 and 1.4

[Vikas Saurabh]

Hi,

Oak's facet implementation had these two issues [0], [1]. I would like
to backport those to 1.6 and 1.4 branch.

Thanks,
Vikas


[0]: OAK-6750 - Facet for relative properties not working
[1]: OAK-6792 - xpath support for facet queries
