显示数据类型token_count的字段值

Question

我有以下映射：

   "fullName" : {
            "type" : "text",
            "norms" : false,
            "similarity" : "boolean",
            "fields" : {
              "raw" : {
                "type" : "keyword"
              },
              "terms" : {
                "type" : "token_count",
                "analyzer" : "standard"
              }
            }
          }

我想显示value of terms字段。当我执行以下操作时，我得到的是fullName值，而不是terms值

GET /_search
{"_source": ["fullName","fullName.terms"], 
    "query": {
        "bool" : {
            "must" : {
                "script" : {
                    "script" : {
                        "source": "doc['fullName.terms'].value != 3,
                        "lang": "painless"
                     }
                }
            }
        }
    }
}

我怎么才能得到它呢？

您需要将令牌计数配置为已存储- Here documentation

您应该修改您的映射：

"terms" : {
    "type" : "token_count",
    "analyzer" : "standard",
    "store": true
}

然后，要检索该值，您需要在查询中显式地请求存储值：( here documentation )

GET /_search
{
  "_source": [
    "fullName"
  ],
  "stored_fields": [
    "fullName.terms"
  ],
  "query": {
    "bool": {
      "must": {
        "script": {
          "script": {
            "source": "doc['fullName.terms'].value != 3",
            "lang": "painless"
          }
        }
      }
    }
  }
}
