Hi All,

I am using elasticsearch-spark-13\_2.10 artifact for storing documents in ES. I have "INITIATIVE\_CODE" field in my document which is used as \_id field using below setting,

> JavaEsSpark.saveToEs(final\_df, "rd\_innovation\_item/innovation\_item",  
> ImmutableMap.of("es.mapping.id","INITIATIVE\_CODE"));

From the input the initiative\_code has two documents,

```
US 2987621 31222335 27/07/2016 00:00:00 N 06/02/2017 01:58:54 07/02/2017 08:14:37
US 2987621 29424184 28/07/2016 00:00:00 N 06/02/2017 01:59:14 07/02/2017 08:14:37

```

After the completion of the job I found only one record. **Is there way to index these two documents in the ES?**

Please kindly share your thoughts on this.

Many Thanks,  
Ganeshbabu R

Since you have set the INITIATIVE\_CODE field as the id, any following documents that have the same value in that field will be indexed over the previous document. You will need to find a unique field to be used as your document id if you want to index both of these documents as separate documents.
