Elasticsearch：如何查询长字段以进行精确匹配

Question

我的文档具有以下映射属性：

"sid" : {"type" : "long", "store": "yes", "index": "no"},

此属性的每条记录只有一个值。我想查询此属性。我尝试了以下查询：

{
    "query" : {
        "term" : {
             "sid" : 10
        }
    }
}

{
    "query" : {
        "match" : {
             "sid" : 10
        }
    }
}

但是，我没有得到任何结果。我确实有一个 sid 等于 10 的文件。我做错了什么？我想查询此属性是否完全匹配。

感谢和问候。

引自the documentation：

index: Set to analyzed for the field to be indexed and searchable after being broken down into token using an analyzer. not_analyzed means that its still searchable, but does not go through any analysis process or broken down into tokens. no means that it won’t be searchable at all (as an individual field; it may still be included in _all). Setting to no disables include_in_all. Defaults to analyzed.

因此，通过将 index 设置为 no，您无法单独搜索该字段。因此，您需要从 index 中删除 no 并选择其他内容，或者您可以使用 "include_in_all":"yes" 并使用不同类型的查询：

  "query": {
    "match": {
      "_all": 10
    }
  }
