Hi there, I understand a geo-point can be mapped based on two fields : "lat", "long". However my fields are name "longitude" and "latitude". I'm using the river plugin for couchdb and I cannot really rename those fields before indexing. And those fields are part of an item in an array: "items": [ { "item\_id" : "abcd", "location": { "longitude": 145.7711, "latitude": -16.92359 } }, { "item\_id" : "efgh", "location": { "longitude": 149.6611, "latitude": -19.94098 } } ] So, any idea how I can rename those fields? And eventually map it to a geo point ([http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-geo-point-type.html](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-geo-point-type.html))?

You could may be try to use script filters and add on the fly lat and lon fields or a String representing your point.

Thanks for your reply. I know I tried that, but it's in an array, so Iw ould need to iterate or something, because trying to map the path leads to an error if there is an array: Here, items is an array: ctx.doc.items.location.longitude That's why i'm looking for an alternative solution.
