在elasticsearch中bulk的概念，其实和sql中的group by有异曲同工的作用。

The bulk API allows one to index and delete several documents in asingle request. Here is a sample usage:

import static org.elasticsearch.common.xcontent.XContentFactory.*;BulkRequestBuilder bulkRequest = client.prepareBulk();// either use client#prepare, or use Requests# to directly build index/delete requestsbulkRequest.add(client.prepareIndex("twitter", "tweet", "1")        .setSource(jsonBuilder()                    .startObject()                        .field("user", "kimchy")                        .field("postDate", new Date())                        .field("message", "trying out Elasticsearch")                    .endObject()                  )        );bulkRequest.add(client.prepareIndex("twitter", "tweet", "2")        .setSource(jsonBuilder()                    .startObject()                        .field("user", "kimchy")                        .field("postDate", new Date())                        .field("message", "another post")                    .endObject()                  )        );BulkResponse bulkResponse = bulkRequest.get();if (bulkResponse.hasFailures()) {    // process failures by iterating through each bulk response item}
