Elasticsearch之curl删除

Elasticsearch之curl删除索引库

   删除,某一条数据,如下

[hadoop@master elasticsearch-2.4.0]$ curl -XDELETE http://master:9200/zhouls/user/1{"found":true,"_index":"zhouls","_type":"user","_id":"1","_version":4,"_shards":{"total":2,"successful":2,"failed":0}}[hadoop@master elasticsearch-2.4.0]$ [hadoop@master elasticsearch-2.4.0]$ [hadoop@master elasticsearch-2.4.0]$ 

  得到

  

   如果我们想要删除的文档存在,则found属性值为true,_version属性的值+1。

  如果我们想要删除的文档不存在,found属性值false,但是_version属性的值依然会+1,这个就是内部管理的一部分,它保证了我们在多个节点间的不同操作的顺序都被正确标记了。

  比如,如下,是我们在上面已经删除了的文档,可见,它依然还是+1。

[hadoop@master elasticsearch-2.4.0]$ curl -XDELETE http://master:9200/zhouls/user/1{"found":true,"_index":"zhouls","_type":"user","_id":"1","_version":4,"_shards":{"total":2,"successful":2,"failed":0}}[hadoop@master elasticsearch-2.4.0]$ [hadoop@master elasticsearch-2.4.0]$ [hadoop@master elasticsearch-2.4.0]$ curl -XDELETE http://master:9200/zhouls/user/1{"found":false,"_index":"zhouls","_type":"user","_id":"1","_version":1,"_shards":{"total":2,"successful":2,"failed":0}}[hadoop@master elasticsearch-2.4.0]$ [hadoop@master elasticsearch-2.4.0]$ [hadoop@master elasticsearch-2.4.0]$ curl -XDELETE http://master:9200/zhouls/user/1{"found":false,"_index":"zhouls","_type":"user","_id":"1","_version":2,"_shards":{"total":2,"successful":2,"failed":0}}[hadoop@master elasticsearch-2.4.0]$ [hadoop@master elasticsearch-2.4.0]$ [hadoop@master elasticsearch-2.4.0]$ curl -XDELETE http://master:9200/zhouls/user/1{"found":false,"_index":"zhouls","_type":"user","_id":"1","_version":3,"_shards":{"total":2,"successful":2,"failed":0}}[hadoop@master elasticsearch-2.4.0]$ [hadoop@master elasticsearch-2.4.0]$ [hadoop@master elasticsearch-2.4.0]$ curl -XDELETE http://master:9200/zhouls/user/1{"found":false,"_index":"zhouls","_type":"user","_id":"1","_version":4,"_shards":{"total":2,"successful":2,"failed":0}}[hadoop@master elasticsearch-2.4.0]$ [hadoop@master elasticsearch-2.4.0]$ 

  注意:删除一个文档不会立即生效,它只是被标记成已删除。es将会在你之后添加更多索引的时候才会在后台进行删除内容的清理
