Hi  
I need to run a search query across multiple indices (say, `idx-users` and `idx-meta`). The mapping for each is different.  
`idx-users` has a nested field (path: `staysAt`, field: `staysAt.street`), while `idx-meta` doesn't have this field.  
I'm trying to do a simple search (`/idx-users,idx-meta/_search`), with `function_score` query, in which one of the `functions` is:

```auto
{
          "filter": {
            "nested": {
              "path": "staysAt",
              "query": {
                "term": {
                  "staysAt.street": "MGRoad"
                }
              }
            }
          },
          "weight": 1.5
}

```

Upon running this query, I'm facing the following error:

```auto
{
              "index": "idx-meta",
              "caused_by": {
                "type": "illegal_state_exception",
                "reason": "[nested] failed to find nested object under path [staysAt]"
              }
}

```

How can I successfully run my query, and have scores according to whichever filter functions match?

Elasticsearch: v7.0.0

I think what you are looking for is "ignore\_unmapped" parameter.  
**ignore\_unmapped:**  
Indicates whether to ignore an unmapped `path` and not return any documents instead of an error. Defaults to `false` .  
If `false` , Elasticsearch returns an error if the `path` is an unmapped field.  
You can use this parameter to query multiple indices that may not contain the field `path` .

Check the Doc: [https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-nested-query.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-nested-query.html)
