Multi_terms 聚合给我一个错误

Question

我正在尝试在 Windows 10 上使用 ElasticSearch v. 7.11.1。我不知道如何使 multi_terms 聚合工作。此查询：

{
  "aggs": {
    "test_agg": {
      "multi_terms": {
        "terms": [{
          "field": "JobTitle.keyword" 
        }, {
          "field": "AboutMe.keyword"
        }]
      }
    }
  }
}

给我这个：

{
  "error": {
    "root_cause": [
      {
        "type": "parsing_exception",
        "reason": "Unknown aggregation type [multi_terms] did you mean [rare_terms]?",
        "line": 4,
        "col": 22
      }
    ],
    "type": "parsing_exception",
    "reason": "Unknown aggregation type [multi_terms] did you mean [rare_terms]?",
    "line": 4,
    "col": 22,
    "caused_by": {
      "type": "named_object_not_found_exception",
      "reason": "[4:22] unknown field [multi_terms]"
    }
  },
  "status": 400
}

但是这个查询：

{
  "aggs": {
    "test_agg": {
      "terms": 
            {
                "field": "JobTitle.keyword",
                "size": "10"
            }
    }
  }
}

有效。我做错了什么？

Answer 1

问题是，您使用的是 Elasticsearch 7.11。

如您在 Release notes 中所见，他们在 7.12.0 中添加了 multi_terms 功能。
