Elasticsearch之增删改查

Elasticsearch的增删改查相当于CRUD,index,delete,update,get

1.增加

put.sh如下代码

curl -X PUT  -uuser:password -H 'Content-Type: application/json'  'http://localhost:port/test/_doc/1' -d'
{
        "user": "kumufengchun",
        "country":   "中国",
        "prov":   "福建",
        "city":   "unknown"
}
'

返回结果

[kumufengchun@localhost ~/es_test]$ ./put.sh
{"_index":"test","_type":"_doc","_id":"1","_version":1,"result":"created","_shards":{"total":2,"successful":2,"failed":0},"_seq_no":10,"_primary_term":1}

2.删除

delete.sh如下代码

curl -X POST  -uuser:password -H 'Content-Type: application/json'  'http://localhost:port/test/_delete_by_query' -d'
{
  "query" : {
    "term" : {
      "user" : {
        "value": "kumufengchun"
      }
    }
  }
}
'

返回结果

[kumufengchun@localhost ~/es_test]$ ./delete.sh
{"took":171,"timed_out":false,"total":1,"deleted":1,"batches":1,"version_conflicts":0,"noops":0,"retries":{"bulk":0,"search":0},"throttled_millis":0,"requests_per_second":-1.0,"throttled_until_millis":0,"failures":[]}

3.修改

update.sh如下代码

curl -X POST  -uuser:password -H 'Content-Type: application/json'  'http://localhost:port/test/_doc/1/_update' -d'
{
  "script" : {
    "source":"ctx._source.city=params.city",
    "lang":"painless",
    "params" : {
      "city" : "厦门"
    }
  }
}
'

返回结果

[kumufengchun@localhost ~/es_test]$ ./update.sh
{"_index":"test","_type":"_doc","_id":"1","_version":2,"result":"updated","_shards":{"total":2,"successful":2,"failed":0},"_seq_no":13,"_primary_term":1}

4.查询

select.sh如下代码

curl -X GET  -uuser:password -H 'Content-Type: application/json'  'http://localhost:port/test/_search' -d'
{
  "query" : {
    "term" : {
      "prov" : {
        "value": "福建"
      }
    }
  }
}
'

返回结果

[kumufengchun@localhost ~/es_test]$ ./select.sh
{"took":3,"timed_out":false,"_shards":{"total":5,"successful":5,"skipped":0,"failed":0},"hits":{"total":1,"max_score":1.0,"hits":[{"_index":"test","_type":"_doc","_id":"1","_score":1.0,"_source":
{
        "user": "kumufengchun",
        "country":   "中国",
        "prov":   "福建",
        "city":   "unknown"
}
}]}}
