为什么 elasticsearch 给我的结果与我的查询不匹配

Question

我正在尝试确保只返回 "relationship_type":"group" 的文档，但为什么 "relationship_type: "event" 也会返回分数与 "relationship_type":"group" 相似的文档？另外，为什么我的源过滤不起作用？

我对开发工具的要求

POST get-together/_search?size=5

{
  "query": {
         "match": { "relationship_type":   "group"        }
  },
  "fields": ["relationship_type"],
  "_source": false  
}

响应，请注意我必须限制大小，否则它会出于某种原因返回所有内容。我的来源未被过滤，最后一个文档与我的查询不匹配

  "timed_out" : false,
  "_shards" : {

      }
    ]
  }
}

这就是我对 relationship_type 字段的映射

您需要删除 POST 和 JSON 查询之间的空行，否则不会考虑该查询。

在 Dev Tools 中，它应该如下所示：

POST get-together/_search?size=5
{   <---- no empty line here
  "query": {
         "match": { "relationship_type":   "group"        }
  },
  "fields": ["description"],
  "_source": false  
}

为什么 elasticsearch 给我的结果与我的查询不匹配

Why is elasticsearch giving me results that don't match my query
