Elasticsearch 分页来源 - 大小结果 window 太大

Elasticsearch Pagination From - Size Result window is too large

我想为我的文档创建页面,每个页面应该有 1000 个结果。

文档大小:95.000 个文档

所以从产品编号 10k 开始,我想从那时起得到 1K 个结果,但是,使用这个查询,我得到了下面提到的错误

查询:

this.es.search({
  index: indexName,
  type: type,
  from: 10000,
  size: 1000,
  body: {}
});

错误:

{
    "msg": "[query_phase_execution_exception] Result window is too large, from + size must be less than or equal to: [10000] but was [16000]. See the scroll api for a more efficient way to request large data sets. This limit can be set by changing the [index.max_result_window] index level setting.",
    "path": "/products/Product/_search",
    "query": {},
    "body": "{\"from\":10000,\"size\":1000}",
    "statusCode": 500,
    "response": "{\"error\":{\"root_cause\":[{\"type\":\"query_phase_execution_exception\",\"reason\":\"Result window is too large, from + size must be less than or equal to: [10000] but was [16000].

}

如何提高分页结果/限制?

也欢迎任何其他方法,谢谢。

如错误所示,Elastic 将只显示 10000 行。

所以要显示更多的数字,您需要使用 scroll 函数

https://www.elastic.co/guide/en/elasticsearch/reference/current/search-request-scroll.html

可以在此处找到带有滚动的 js 搜索示例。

基于 elasticsearch 文档https://www.elastic.co/guide/en/elasticsearch/reference/current/search-request-from-size.html

Note that from + size can not be more than the index.max_result_window index setting which defaults to 10,000

作为替代,您可以尝试使用 scrollsearchAfter。对于更实时的查询,searchAfter更合适。

滚动文档 https://www.elastic.co/guide/en/elasticsearch/reference/current/search-request-scroll.html

SearchAfter 文档 https://www.elastic.co/guide/en/elasticsearch/reference/current/search-request-search-after.html

好吧,我可以使用这个 CURL 增加分页限制

curl -XPUT "http://localhost:9200/my_index/_settings" -d '{ "index" : { "max_result_window" : 500000 } }'

增加max_result_window如下,有效

PUT indexName/_settings
{
  "index": {
    "max_result_window": 10000000
  }
}
