[Photon] Reverse lookup can be inaccurate

[Stephen - junkmail]

Thank you! I had not seen those options as I was only looking at 
documentation under the latest release. I have the server processing now 
on admin only.

I do program in Java but I have no experience with ElasticSearch. This 
summer I may have some time to submit some PRs.
