title: Raw and Keyword in subfields
body: <p>I created an index with this mapping :</p>
  
  <pre><code> "movies2": {
      "aliases": {},
      "mappings": {
        "movie": {
          "properties": {
            "fields": {
              "properties": {
                "actors": {
                  "type": "text",
                  "fields": {"raw": {"type": "keyword"}}
                },
                "directors": {
                  "type": "text",
                  "fields": {"raw": {"type": "keyword"}}
                },
                "genres": {
                  "type": "text",
                  "fields": {"raw": {"type": "keyword"}}
                },
  </code></pre>
  
  <p>But later when I tried to check the mapping with :
  <a href="http://localhost:9200/movies2/?pretty" rel="nofollow noreferrer">http://localhost:9200/movies2/?pretty</a></p>
  
  <p>I found out that the mapping was converted to :</p>
  
  <pre><code> "genres": {
                  "type": "text",
                  "fields": {"keyword": {"type": "keyword"}}
  
  
        },
  </code></pre>
  
  <p>I am using ElasticSearch 7.0 . Is the "raw" keyword not used anymore? Is it the default behaviour to convert it to "keyword" when we create an index?</p>
  
  <p>Regards,</p>
