Question

我有以下短语：

从来没有发生在我身上 - 巴塞罗那的梅西球员对克里斯蒂亚诺罗纳尔多的真实明星马德里感谢尤文球迷的欢呼。

一个名为Player的简单弹性搜索文档：

"firstName": {
   "localizedValues": {
      "de": "",
      "en": "Cristiano"
   }
},
"lastName": {
   "localizedValues": {
      "de": "",
      "en": "Ronaldo"
   }
}
"teamAssociations": [
   {
      "active": true,         
      "teamName": {
         "localizedValues": {
            "de": "",
            "en": "Real Madrid"
         }
      }
]

我尝试做的是一种简单的映射方法，尝试找一个为球队效力的球员，在这种情况下我想得到克里斯蒂亚诺罗纳尔多和梅西，如果找到了那个短语中的球队，那么就可以提高得分以获得更多相关性。

到目前为止我尝试过：

{
    "query": {
        "bool": {
            "must": {
                "multi_match" : {
                "query":    " It's never happened to me – Messi to Cristiano Ronaldo star of Real Madrid thanks Juve fans for ovation ", 
                "fields": [ "firstName.localizedValues.*", "lastName.localizedValues.*", "teamAssociations.teamName.*^3" ],
                "type":       "cross_fields",
                "analyzer":   "english"
             }
            }
        }
    }
}

但是那也是其他为Read Madrid效力的球员，我不想要。同样在那个标题中我可能没有球队名称，只有球员，因此球队应该是可选的，但如果找到则很重要。

我该如何解决这个问题？

提前感谢您的帮助。

我们的想法是在should子句中添加可选字段。试试这样的事情

{
  "query": {
    "bool": {
      "must": {
        "multi_match": {
          "query": " It's never happened to me – Messi to Cristiano Ronaldo star of Real Madrid thanks Juve fans for ovation ",
          "fields": [
            "firstName.localizedValues.*",
            "lastName.localizedValues.*"
          ],
          "type": "cross_fields",
          "analyzer": "english"
        }
      },
      "should": {
        "multi_match": {
          "query": " It's never happened to me – Messi to Cristiano Ronaldo star of Real Madrid thanks Juve fans for ovation ",
          "fields": [
            "teamAssociations.teamName.*"
          ],
          "type": "cross_fields",
          "analyzer": "english"
        }
      }
    }
  }
}
