为什么Elasticsearch给我的结果与我的查询不匹配

我试图确保仅"relationship_type":"group"返回文档，但为什么还"relationship_type: "event"返回分数相似的文档"relationship_type":"group"？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，否则出于某种原因它将返回所有内容。我的来源没有被过滤，最后一个文档与我的查询不匹配

  }
}

这就是我对该relationship_type字段的映射

值

您需要删除POST和JSON查询之间的空行，否则不考虑该查询。

在开发工具中，它应如下所示：

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