I have an index where from an ip field from the data source I have added the filter
geoip to logstash that get the data. I got in my index a brand new bunch of field about latitude, longitude, city... but it's not usable as it is to pinpoint on a map since the long/lat are of type string or number.
I added to the mapping of this index a new field of type
geo_point and I would like now to fill it with the concatenation of "lon"+","+"lat" like the seconde exemple here.
Can I do that easily ?
