Dynamic ElasticSearch mapping using Elastic4s
You can't do what you want in the elastic4s Scala API at the moment. But you can create a dynamic template in the Java API and use the Scala API for the rest of your calls.
The dynamic template can be set to use a regex and apply a mapping. But since you will really know your countries in advance (there's only ~200) why not just spend the time and make a mapping?
This is how the elastic4s documentation says to do it : (https://github.com/sksamuel/elastic4s/blob/master/guide/index.md)
val settings = ImmutableSettings.settingsBuilder().put("cluster.name","blah")val client = ElasticClient.remote("ip.address",portNum)client.execute { index into "indexname/indexType" doc StringSource(jsonDoc.toString)}where StringSource extends DocumentSourceIf you able to marshall your input into JSON, this is the best way to do it.
