Elasticsearch mapping definitions for full-text Search and keyword search fields

Before ES5.0 we defined the fields that required keyword search:

{"  field name": {      "type": "string",      "index": "Not_analyzed"  }    }

　

Full-Text Search:

{"  field name": {      "type": "String"  }    }

　　

ES 5+:

Keyword search:

{"  field name": {      "type": "Keyword"  }    }

　　

Full-Text Search:

{"  field name": {      "type": "Text"  }    }

　

Individuals feel that the change is clearer and more concise than before.

The reason for the change and more details can be read the official blog
