Elasticsearch之curl删除索引库

 

 

 

 

 

 

 　　删除，某一条数据，以下

[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]$ 

 

 

　　获得

 

 

 

　　

 

 

 　　若是咱们想要删除的文档存在，则found属性值为true，_version属性的值+1。

　　若是咱们想要删除的文档不存在，found属性值false，可是_version属性的值依然会+1，这个就是内部管理的一部分，它保证了咱们在多个节点间的不一样操做的顺序都被正确标记了。

　　好比，以下，是咱们在上面已经删除了的文档，可见，它依然仍是+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]$

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