Elasticsearch update_by_query 语句使用记录

使用如下

POST 索引/索引类型/_update_by_query
{
  "script": {
    "source": "ctx._source['修改的字段名'] = '修改后的值'"
  },
  "query": {
    "bool": {
      "must": [
        {
          "term": {
            "查询条件此处为字段名": "字段的值"
          }
        }
      ],
      "must_not": [],
      "should": []
    }
  }
}

这段代码的意思是，查询index索引，type等于index_type中数据满足field=value的数据，修改其中field=test

执行代码可执行的再此

POST index/index_type/_update_by_query
{
  "script": {
    "source": "ctx._source['field'] = 'test'"
  },
  "query": {
    "bool": {
      "must": [
        {
          "term": {
            "field": "value"
          }
        }
      ],
      "must_not": [],
      "should": []
    }
  }
}
