Implement a new Boundary index builder

[ncolomer]

This specialized index aims to index multi-level boundaries (country / state / province / city) in order to query for region memberships of a location.

This implies following tasks:

• implement the Relation entity in the EntityDao
• index Relations in the main index
• implement the Boundary specialized index builder (see the boundary=administrative wiki page)

Hi,

I was wondering if this project is still maintained.
I saw in the documentation that relations are still not supported.
Can I help out?
I want to try and create a GeoServer that is using elastic search and OSM data.
Found another project that uses Elastic Search as a data source for GeoServer and the only missing piece I need to find is a way to get OSM data into ES database.
Currently I'm doing it in my project using C# code but I think using Osmosis is probably a better approach since this is what the OSM community is familiar with.
