Elasticsearch之CURL命令的DELETE

 

 

 

 

　　也可以看我寫的下面的博客

Elasticsearch之curl刪除索引庫

 

 

 

 

 

 

 　　刪除，某一條數據，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

 

 

 

　　

 

 

 　　如果我們想要刪除的文檔存在，則found屬性值為true，_version屬性的值+1。

　　如果我們想要刪除的文檔不存在，found屬性值false，但是_version屬性的值依然會+1，這個就是內部管理的一部分，它保證了我們在多個節點間的不同操作的順序都被正確標記了。

　　比如，如下，是我們在上面已經刪除了的文檔，可見，它依然還是+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：刪除一個文檔不會立即生效，它只是被標記成已刪除。es將會在你之后添加更多索引的時候才會在后台進行刪除內容的清理。
