elasticsearch - 尝试聚合时获取 “Field data loading is forbidden”

Question

我正在尝试做一个简单的唯一聚合，但出现此错误:

java.lang.IllegalStateException: Field data loading is forbidden on eid

这是我的查询:

POST /logstash-2016.06.*/Nginx/_search
{
  "query": {
    "bool": {
      "filter":  [
          {
            "term": { 
              "pid": "1"
            }
          },
          {
            "term": { 
              "cvprogress": "0"
            }
          },
          {
          "range" : {
              "ServerTime" : {
                  "gte" : "2016-06-28T00:00:00"
              }
          }
          }
      ]
    }
  },
    "aggs": {
          "distinct_colors" : {
              "cardinality" : {
                "field" : "eid"
              }
          }
        }

}

在https://github.com/elastic/elasticsearch/issues/15267遍历整个线程之后，有效的方法是添加.raw

像这样:

"aggs": {
          "distinct_colors" : {
              "cardinality" : {
                "field" : "eid.raw"
              }
          }
        }
