With much sweat I could build a Bulk Request, on the new Java API 8.1.0, like this

```auto
// build request
ArrayList<BulkOperation> bulkOperations = new ArrayList<BulkOperation>();
BulkOperation bulkOperation = BulkOperation.of(b -> b.index(i -> i.index(indexes).id(qesdocument.idValue()).document(jsonData)) );
bulkOperations.add(bulkOperation);

// run request
bulkResponse = client.bulk(b -> b.index(indexes).operations(bulkOperations));

// handle errors
if (bulkResponse.errors()) { .....

```

When issued on a bulk of hundreds of documents, not all of them made it to Elasticsearch.  
**There were errors , on some documents , somewhere ...**

How can I **handle fine grained errors** to investigate what went wrong , just like what was provided in in the HLRC ?

You have to iterate over the response hits.  
You can do that with a stream and a filter to only collect the hits which have an error.

Ok, did this, (old style programming)

```auto

          if (bulkResponse.errors()) {

              System.out.println("Erreur occured");

              for (BulkResponseItem bulkResponseItem : bulkResponse.items()) {
                  if (bulkResponseItem.error() != null) {
                      System.out.println("Erreur id", bulkResponseItem.id());
                      System.out.println("Erreur seqNo", bulkResponseItem.seqNo());
                      System.out.println("Erreur result", bulkResponseItem.result());
                      System.out.println("Erreur type", bulkResponseItem.error().type());
                      System.out.println("Erreur reason", bulkResponseItem.error().reason());
                      System.out.println("Erreur caused by", bulkResponseItem.error().causedBy().reason());
                      System.out.println("Erreur String", bulkResponseItem.error().toString());
                      System.out.println("Erreur stackTrace", bulkResponseItem.error().stackTrace());
                  }
              }

          }

```

@ivanqwam can you elaborate on that? What exactly are you referring to? This can be valuable information to improve the new client.

Thanks.
