Question

我想为我的文档提供页面，每页应该有1000个结果。

文件大小：95.000个文档

所以从产品编号10k开始，我希望从那一点获得1K结果，但是，使用此查询，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]. See the scroll api for a more efficient way to request large data sets.

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.\"}}]},\"status\":500}"
}

如何增加分页结果/限制？

欢迎任何其他方法，谢谢。

Answer 1

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

请注意，from + size不能超过index.max_result_window 索引设置，默认为10,000

另外，您可以尝试使用scroll或searchAfter。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

Answer 2

由于错误显示Elastic只显示10000行。

因此要显示超过该数字，您需要使用scroll功能

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

可以在此处找到带滚动的js搜索示例。

async await with elasticsearch search/scroll

Answer 3

好吧，我可以使用此CURL增加分页限制

// GET: api/currencies
[HttpGet]
[ResponseCache(Duration = 60)]
public async Task<IEnumerable<GetCurrencyResponse>> Get()
{
    var currencies = await _currencyService.GetCurrenciesAsync();

    return currencies;
}

Answer 4

按如下所示增加max_result_window，就可以了

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

Elasticsearch Pagination From - Size Result窗口太大
