Elasticsearch报Result window is too large问题处理

在使用Elasticsearch进行search查询时,出现了Result window is too large的问题。
报错如下:

QueryPhaseExecutionException[Result window is too large, from + size must be less than or equal to: [10000] but was [10200]. 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 parameter.]; }{[Sgi3DlLvRimb3RlcDFJI2Q][goagain_index_order_v1][9]: RemoteTransportException[[node_l-qgoagainesdata3.ops.cn2.qunar.com][10.90.53.180:9300][indices:data/read/search[phase/query]]]; nested: QueryPhaseExecutionException[Result window is too large, from + size must be less than or equal to: [10000] but was [10200]. 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 parameter.]; }

从上面的报错信息,可以看到ES提示我结果窗口太大了,目前最大值为10000,而我却要求给我10200。并且在后面也提到了要求我修改index.max_result_window参数来增大结果窗口大小。
修改方法如下:

curl -XPUT http://localhost:9200/indexName/_settings -d ‘{ “index” : { “max_result_window” : 100000}}’

需要注意的是,indexName这里是我ES索引的名字,因此你需要它替换成你对应的索引名称进行修改。
