http 400 error Elasticsearch查询检索数组中包含任何关键字的文档

Question

我有大量的关键字写在一个文件中。我将它们放入一个数组中，并尝试对数组中的每个项运行一个查询，并检索包含任何关键字的文档。它显示了返回文档的数量，其中只有50个，最后我得到了几个错误。 这是我的代码：

关键字的子集：

C0001396    SYNDROME STOKES-ADAMS
C0001396    Syndrome, Adams-Stokes
C0001396    Syndrome, Stokes-Adams
C0002962    3-12 ANGINAL SYNDROMES
C0002962    ANGINA

代码：

^{pr2}$

错误：

    raise HTTP_EXCEPTIONS.get(status_code, TransportError)(status_code, 
error_message, additional_info)
elasticsearch.exceptions.RequestError: <exception str() failed>

知道为什么会这样吗？ 谢谢

elasticsearch查询的格式不正确。我把它改成了下面的，它成功了！公司名称：

  doc = {
    "query": { 
        "multi_match": {
                "query": x,
                "type": "phrase",
                "fields": ["title", "description"],   
                "operator": "and"
               }
             }
          }
