Question

我正在寻找一种方法来返回_id小于给定_id的所有文档，但是我没有检索到。我正在尝试的查询是：

 curl -XPOST "http://localhost:9200/smartjn/feed_details/_search" -d' {"query":{"range":{"uid":{"gte":"56f43c0344fc86e73b1170b0"}}}}'
This gives me result as: 
{"took":21,"timed_out":false,"_shards":{"total":5,"successful":5,"failed":0},"hits":{"total":0,"max_score":null,"hits":[]}}

但是，我可以看到10K记录中有_id＆gt;我上面提到的。我知道如何实现这一目标。

在MongoDB中我使用

 '_id' => [
'$lt' =>
new MongoDB\BSON\ObjectId($_GET['lastid'])
]

实现同样的目标。

当我执行测试时，我获得了成功的结果。你可以发布字段uid的索引映射吗？ localhost:9200/smartjn/_mapping/feed_details/field/uid

  pancake$ curl -XGET localhost:9200/test_index/test_type2/_search -d '{"query":{"range":{"uid":{"gte":"56f43c0344fc86e73b1170b0"}}}}'

 {"took":11,"timed_out":false,"_shards":
 {"total":5,"successful":5,"failed":0},"hits":
 {"total":4,"max_score":1.0,"hits": [
    {"_index":"test_index","_type":"test_type2","_id":"AVeLab8ILs6L_WBjvpfv","_score":1.0,"_source":{"uid":"56f43c0344fc86e73b1170b0"}},
    {"_index":"test_index","_type":"test_type2","_id":"AVeLadPoLs6L_WBjvpfx","_score":1.0,"_source":{"uid":"56f43c0344fc86e73b1170b2"}},
    {"_index":"test_index","_type":"test_type2","_id":"AVeLadp4Ls6L_WBjvpfy","_score":1.0,"_source":{"uid":"56f43c0344fc86e73b1170b3"}},
    {"_index":"test_index","_type":"test_type2","_id":"AVeLacwhLs6L_WBjvpfw","_score":1.0,"_source":{"uid":"56f43c0344fc86e73b1170b1"}}
 ]}}

快速问题，您问过＆＃34;我正在寻找一种方法来返回_id 小于给定_id但仍未能检索到的所有文档。＆＃34;然后您使用 gte （大于或等于）查询。你在寻找什么结果？

elasticsearch查询返回mongodb文件少于_id
