ES报错Result window is too large问题处理
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 : import requests
In : requests.get('http://127.0.0.1:9200/cmdb-now/_search?page=1&size=10000000').json()
Out:
{
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: but was . See the scroll api for a more efficient way to request large data sets. This limit can be set by changing the 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: but was . See the scroll api for a more efficient way to request large data sets. This limit can be set by changing the 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。
