Spring data elasticsearch bulk index and delete

I'm new to the community so I apologise if I do something wrong.

I'm using spring data elasticsearch (2.0.4/2.4) And I would like to make a bulk insert and delete. But ElasticsearchTemplate only contains a method bulkInsert

@Override
public void bulkIndex(List<IndexQuery> queries) {
    BulkRequestBuilder bulkRequest = client.prepareBulk();
    for (IndexQuery query : queries) {
        bulkRequest.add(prepareIndex(query));
    }
    BulkResponse bulkResponse = bulkRequest.execute().actionGet();
    if (bulkResponse.hasFailures()) {
        Map<String, String> failedDocuments = new HashMap<String, String>();
        for (BulkItemResponse item : bulkResponse.getItems()) {
            if (item.isFailed())
                failedDocuments.put(item.getId(), item.getFailureMessage());
        }
        throw new ElasticsearchException(
                "Bulk indexing has failures. Use ElasticsearchException.getFailedDocuments() for detailed messages ["
                        + failedDocuments + "]", failedDocuments
        );
    }
}

So I have created a bulk method to handle both but I can't access the method prepareIndex which is private.

Are you aware of any solution to, in one bulk, index and delete documents or should I use reflection to change visibility of the prepareIndex method or is there any easy way to create an indexRequest from a model/POJO?

it depends of elastic version. For last version of elastic you can use "Delete by query API"

Deletes documents that match the specified query.

Not sure which versions you mean with

(2.0.4/2.4)

Currently there is no possibility for bulk deletes. And no combination of different operations like index/update in one request.

Can you file an issue in Jira to add support for bulk delete and a possibility to have different operations in one call? Though this won't make it into the next release, I'm afraid.
