CouchDB, Elasticsearch - Problem creating index

Question

Programming

Hey Habr! Help with Elasticsearch.

I am using CouchDB, Elasticsearch and the elasticsearch-river-couchdb plugin to communicate between them. There are objects in the database with a name

field of type object :

{
  "name": {
     "first": "Ivan",
     "last": "Ivanov"
  }
}

There are also objects where the name field is of type string:

{
  "name":"Ivan Ivanov"
}

Problem: The index is only created for objects where the name field is of type object .
The mapping for the name field specifies the object type.

Question: is it possible to somehow specify type 2 for a field?

If not, then perhaps you should create 2 indexes for 1 database, and in each index take into account objects with the desired field type?

I tried to turn such a thing, but the idea was not crowned with success. Created 2 indexes and set the following settings for them.

For the first:

-XPUT 'site.ru:9200/_river/dev_idx/_meta' -d '{
     "type" : "couchdb",
     "couchdb" : {
  "host" : "127.0.0.1",
         "port" : 5984,
         "user" : "User",
         "password" : "Test",
         "db" : "dev",
         "filter" : null
         }
     },
     "index" : {
         "index" : "dev",
         "type" : "dev",
         "bulk_size" : "100",
         "bulk_timeout" : "10ms"
     }
 }'

For the second:

-XPUT 'site.ru:9200/_river/dev_third/_meta' -d '{
     "type" : "couchdb",
     "couchdb" : {
  "host" : "127.0.0.1",
         "port" : 5984,
         "user" : "User",
         "password" : "Test",
         "db" : "dev",
         "filter" : null,
         
         "ignore_attachments":true
         }
     },
     "index" : {
         "index" : "dev_third",
         "type" : "dev_third",
         "bulk_size" : "100",
         "bulk_timeout" : "10ms"
     }
 }'

As a result: the first index works, the second does not.
