ElasticSearch滾動只返回10條記錄

Question

我用滾動查詢ES，但我仍然有10條記錄，我的查詢如下：

curl -XGET 'http://10.0.0.5:9200/myin/app/_search?scroll=1m' -d '{ 
    "_source": "appAd", 
    "query": { 
    "bool": { 
     "must_not": { 
     "term": { 
      "app.raw": "dt" 
     } 
     } 
    } 
    } 

以下是結果：

"took":467,"_shards":{"total":24,"successful":24,"failed":0},"hits":{"total":760000} ... 

但只返回10條記錄，儘管它達到了760000條。

您將需要使用查詢結果中返回的scroll_id調用scroll API以獲取下一組結果。繼續撥打，直到處理完所有結果。

curl -XGET 'localhost:9200/_search/scroll' -d' 
{ 
    "scroll" : "1m", 
    "scroll_id" : "c2Nhbjs2OzM0NDg1ODpzRlBLc0FXNlNyNm5JWUc1" 
} 
'
