ElasticSearch里根据查询条件更新文档

核心语法，script脚本语言

• 单个字段

POST device/_update_by_query
{
 
 "query": {
   "match": {
      "deviceId": "9327010000104923"
    }
 }, 
  "script": {
    "source": "ctx._source.deleted = 0",
    "lang": "painless"
  }
}

• 多个字段时，source里面的字段用;隔开

POST device/_update_by_query
{
 
 "query": {
   "match": {
      "deviceId": "9327010000104923"
    }
 }, 
  "script": {
    "source": "ctx._source.deleted = 0;ctx._source.aiType = 1",
    "lang": "painless"
  }
}

• 优化语法，script每次会编译，使用param参数，将字段部分固定，节省消耗

POST device/_update_by_query
{
 
 "query": {
   "match": {
      "deviceId": "9327010000104923"
    }
 }, 
  "script": {
    "source": "ctx._source.deleted = params.deleted",
    "params": {
      "deleted": 0
    }, 
    "lang": "painless"
  }
}
