How to enable “numerical detection string”?

2

By setting numeric_detection to true:

PUT my-index
{
  "mappings": {
    "numeric_detection": true
  }
}

, the following fields field1 and field2 will be mapped as float type and long type, rather than text type:

PUT my-index/_doc/1
{
  "field1":   "1.0",
  "field2": "1"
}

  1. Can you recognize certain parts as correct letters and approximate numbers?
PUT my-index
{
  "mappings": {
    "properties": {
      "year":    { "type" : "text" },
      "age":     { "type" : "text", "numeric_detection": true },
      "director":{ "type" : "text", "numeric_detection": true }
    }
  }
}

RESPONSE

{
    "acknowledged": true,
    "shards_acknowledged": true,
    "index": "my-index"
}
  1. If you put in a large number, the correct value is text, and is it recognized as a number recognized as an approximate double or scale float value?
PUT /my-index_doc/1 
{
  "year":    "99999999999999999999",
  "age":     "99999999999999999999.99999999999999999999",
  "director": "ABC"
}
