我在使用Elasticsearch进行search查询的过程中，出现了Result window is too large问题。
这里简单做一个报错复现：
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 | In [ 1 ]: import requests In [ 2 ]: requests.get( 'http://127.0.0.1:9200/cmdb-now/_search?page=1&size=10000000' ).json() Out[ 2 ]: { u 'error' : { u 'failed_shards' : [ { u 'index' : u 'cmdb-now' , u 'node' : u 'ldeZMZRAR6uZpAiIr5QxBQ' , u 'reason' : { u 'reason' : u 'Result window is too large, from + size must be less than or equal to: [10000] but was [10000000]. 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 parameter.' , u 'type' : u 'query_phase_execution_exception' } ], u 'type' : u 'search_phase_execution_exception' }, u 'status' : 500 } |
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10000000。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。
我google了修改方法，命令如下：
| 1 | curl -XPUT http: //127 .0.0.1:9200 /cmdb-now/_settings -d '{ "index" : { "max_result_window" : 100000000}}' |
需要注意的是，cmdb-now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。
