Elasticsearch dynamic template for all specific properties

my data structure is something like this:

{ field: xxx, 
  field2: xxx, 
  attrs: { 
     field3: xxx, 
     field4: xxx, 
     var: { field5: xxx, 
            field6: xxx
     } 
  }
}

I don't know attribute names in var, can I use dynamic mapping (and how) to make every attribute ONLY IN attrs.var.XXX searchable (set index: true)?

You can use the following:

PUT unknown_paths
{
  "mappings": {
    "dynamic_templates": [
      {
        "stored_attrs_vars": {
          "path_match": "attrs.*.*",
          "mapping": {
            "index": true
          }
        }
      },
      {
        "no_index": {
          "path_match": "*",
          "unmatch": "attrs.*.*",
          "mapping": {
            "index": false
          }
        }
      }
      
    ]
  }
}

Note that if there's no actual field type, ES will still guess it for you. So even though you don't know the name of attrs.var, you'll probably know the types of field5 and 6, no?
