Fields based dynamic mapping elasticsearch

Question

Can I use wildcard pattern to determine index analyzer for elasticsearch?

For example: "properties":

{ 
    "0_*" : {"type": "string", "index_analyzer": "standard" } , 
    "1_*" : {"type": "string", "index_analyzer": "my_analyzer"}
}

So now if there is a new field when I index the document like

{
    "0_title" : "some string", // should use standard analyzer
    "1_title" : "my anazlyer string" // should use my_analyzer
}

Is there anyway to achieve this?

Yes , all you need to use is the index template. You can find more information on dynamic template here Using index template , you can inject a rule as follows -

{
  "person": {
    "dynamic_templates": [
      {
        "template_0": {
          "match": "0_*",
          "mapping": {
            "type": "string",
            "index_analyzer": "standard"
          }
        }
      },
      {
        "template_1": {
          "match": "1_*",
          "mapping": {
            "type": "string",
            "index_analyzer": "my_analyzer"
          }
        }
      }
    ]
  }
}
