獲得「場數據加載禁止」試圖聚集

Question

我試圖做一個簡單的獨特聚集的時候，卻收到此錯誤：

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

這是我的查詢：

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" 
       } 
      } 
     } 

} 

Answer 1

在https://github.com/elastic/elasticsearch/issues/15267通過整個線程會後什麼工作是將.RAW

這樣的：

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