ElasticSearch Scroll仅返回10条记录

Question

我用滚动来查询ES，但我仍然有10条记录，我的查询如下：

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

以下是结果：

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

但它只返回10条记录，虽然它达到760000。

您需要使用查询结果中返回的scroll_id调用滚动API，以获取下一组结果。继续通话直到所有结果都已处理完毕。

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