es根据条件删除数据

POST /索引名称/_delete_by_query
{
   "query": {
       "bool": {
           "must_not": [
               {
                   "match": {
                       "test": "字段值"
                   }
               }
           ]
       }
}
}

2.从一个索引数据导入另一个索引里
POST _reindex
{
"source": {
"index": "test_20201207",

"size":5000
},
"dest": {
"index": "test_20201208"
}
}

3.查询索引结构

GET /索引名称/_mapping?pretty

4.查询索引数据

GET /索引名称/_search

5.创建模板

curl -H "Content-Type: application/json" -XPUT "ip:9201/_template/模板名称?pretty" -d '{
"template" : "模板名称*",

"settings" : {
"number_of_shards" : 10,
"number_of_replicas" : 1,
       "index.max_result_window": 1000000000
},
"mappings" : {
"properties" : {
"test1" : {
"type" : "keyword"
},
"test2" : {
"type" : "long"
}

}
}
}'

6.增加或更新数据

PUT /_bulk
{"index":{"_index" : "索引名称","_type" : "_doc","_id" : "1189866394802000"}}
{"test1": "12345", "test2": "889999"}

7.删除索引

DELETE /索引名称

8.修改索引的字段值

POST /索引名称/_update_by_query
{
   "query": {
       "bool": {
           "must": [
               {
                   "match": {
                       "status": "1"
                   }
               }
           ]
       }
