我在使用Elasticsearch進行search查詢的過程當中,出現了Result window is too large
問題。
這裏簡單作一個報錯復現:html
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 }
從上面的報錯信息,能夠看到ES提示我結果窗口太大了,目前最大值爲10000,而我卻要求給我10000000。而且在後面也提到了要求我修改index.max_result_window
參數來增大結果窗口大小。node
我google了修改方法,命令以下:
python
curl -XPUT http://127.0.0.1:9200/cmdb-now/_settings -d '{ "index" : { "max_result_window" : 100000000}}'
須要注意的是,cmdb-now
這裏是我ES索引的名字,所以你須要它替換成你對應的索引名稱進行修改。
