Elasticsearch mapping for Indexing

How to create elasticsearch mapping to index a same string in "analyzed" and "not analyzed" fields.

The default Logstash template makes sure there's a .raw subfield for all string fields, if that helps:

logstash-plugins/logstash-output-elasticsearch/blob/v4.1.2/lib/logstash/outputs/elasticsearch/elasticsearch-template.json#L22-L28


"mapping" : {
  "type" : "string", "index" : "analyzed", "omit_norms" : true,
  "fielddata" : { "format" : "disabled" },
  "fields" : {
    "raw" : {"type": "string", "index" : "not_analyzed", "ignore_above" : 256}
  }
}
