Elasticsearch query_shard_exception无法创建查询

Question

我正在尝试在Elasticsearch 6.2中执行以下查询：

GET my_index/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "term": {
            "published": {
              "value": true,
              "boost": 1
            }
          }
        },
        {
          "query_string": {
            "query": "test",
            "fields": [
              "name",
              "description"
            ]
          }
        }
      ]
    }
  }
}

我收到了这个错误
