分布式搜索elasticsearch java API 之（六）------批量添加删除索引

elasticsearch支持批量添加或删除索引文档，Java api里面就是通过构造BulkRequestBuilder，然后把批量的index/delete请求添加到BulkRequestBuilder里面，执行BulkRequestBuilder。下面是个例子：

[java]  view plain  copy

1. import static org.elasticsearch.common.xcontent.XContentFactory.*;   
2.            
3.         BulkRequestBuilder bulkRequest = client.prepareBulk();   
4.            
5.         bulkRequest.add(client.prepareIndex("twitter", "tweet", "1")   
6.                 .setSource(jsonBuilder()   
7.                             .startObject()   
8.                                 .field("user", "kimchy")   
9.                                 .field("postDate", new Date())   
10.                                 .field("message", "trying out Elastic Search")   
11.                             .endObject()   
12.                           )   
13.                 );   
14.            
15.         bulkRequest.add(client.prepareIndex("twitter", "tweet", "2")   
16.                 .setSource(jsonBuilder()   
17.                             .startObject()   
18.                                 .field("user", "kimchy")   
19.                                 .field("postDate", new Date())   
20.                                 .field("message", "another post")   
21.                             .endObject()   
22.                           )   
23.                 );   
24.                    
25.         BulkResponse bulkResponse = bulkRequest.execute().actionGet();   
26.         if (bulkResponse.hasFailures()) {   
27.             //处理错误   
28.         }
