The `_id` field is not analyzed so you can only retrieve a document if the id matches exactly.

If you have an `id` field within your source with the same value as `_id`, the story can be different, but it depends on how that `id` field is mapped. Can you share your mapping?

thanks mr val you response my question,  
i dont use mapping , but you're idea to create new field with same value as \_id is good idea  
but i must update my data one by one.  
im new using elasticsearch but i read any article if you want to use mapping you must  
reset your data and input again , it is right ??

but if there is no way again,  
cant helped i must trying use mapping

You could do this easily using the [reindex API](https://www.elastic.co/guide/en/elasticsearch/reference/6.2/docs-reindex.html):

```
POST _reindex
{
  "source": {
    "index": "source_index"
  },
  "dest": {
    "index": "new_index"
  },
  "script": {
    "source": "ctx._source.id = ctx._id"
  }
}

```

This will create a new `id` field inside your source having the same value as the `_id` field. However, if your `_id`s are of the form `001_employee` and you're willing to look for all documents whose id ends with `employee`, you might want to change your ids to `employee_001` instead as it is easier to search for prefixes than suffixes.

Does your index contain different data types? Why do you encode `employee` within your id?
