How to not-analyze in ElasticSearch?

Question

I\'ve got a field in an ElasticSearch field which I do not want to have analyzed, i. e. it should be stored and compared verbatim. The values will contain letters, numbers,

Answer 1

keyword analyser can be also used.

// don't actually use this, use "index": "not_analyzed" instead
{
  "my_type": {
    "properties": {
      "my_field1": { "type": "string", "analyzer": "english" },
      "my_field2": { "type": "string", "analyzer": "keyword" }
    }
  }
}

As noted here: https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis-keyword-analyzer.html, it makes more sense to mark those fields as not_analyzed.

But keyword analyzer can be useful when it is set by default for whole index.

UPDATE: As it said in comments, string is no longer supported in 5.X
