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:
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. This limit can be set by changing the [index.max_result_window] index level parameter.‘, u‘type‘: u‘query_phase_execution_exception‘ }, u‘shard‘: 0 } ], u‘grouped‘: True, u‘phase‘: u‘query‘, u‘reason‘: u‘all shards failed‘, u‘root_cause‘: [ { 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. 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:
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。
