Question

我想从Elastic Search获得第10001份文件。

如何克服10k批次限制

http://localhost:9200/_search?size=2&from=9999

给出了这个错误：

{
  "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 [10001]. 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."
      }
    ],
    "type" : "search_phase_execution_exception",
    "reason" : "all shards failed",
    "phase" : "query",
    "grouped" : true,
    "failed_shards" : [
      {
        "shard" : 0,
        "index" : ".kibana",
        "node" : "UWl8qQL8QomaoALoHI3BUw",
        "reason" : {
          "type" : "query_phase_execution_exception",
          "reason" : "Result window is too large, from + size must be less than or equal to: [10000] but was [10001]. 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."
        }
      }
    ],
    "caused_by" : {
      "type" : "query_phase_execution_exception",
      "reason" : "Result window is too large, from + size must be less than or equal to: [10000] but was [10001]. 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
}

Answer 1

如果要获取超过10k的文档，则必须使用Scroll API。

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

Answer 2

告诉我们您的文档是否有任何ID。如果有任何ID，您可以根据ID轻松搜索文档。

这样说吧

GET example/test/_search
{
"query":
{
"match":{
"_id":10001
}
}
}

希望这可能会有所帮助
