org.elasticsearch.search.query.QueryPhaseExecutionException

当查询结果超过 10000 且当前页含 10000 条之后的数据时，报了如下错误：

> Caused by: org.elasticsearch.search.query.QueryPhaseExecutionException: Result window is too large, from + size must be less than or equal to: [10000] but was [100000]. 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 setting.

[这篇博客][1] 中讲了如何通过 *curl* 命令设置 *index.number_of_replicas* 属性。

*windows* 上默认没有 *curl* 命令，不过我发现可以在 *Kibana* 上通过界面就可以设置。

在 *Kibana* => *Management* => *Index Management* 上点击对应的索引，然后在 *Edit settings* 标签可以修改索引设置。

下面是将 *index.max_result_window* 设置为 *1000000* 。

```json
{
    "index.blocks.read_only_allow_delete": "false",
    "index.priority": "1",
    "index.query.default_field": [
        "*"
    ],
    "index.write.wait_for_active_shards": "1",
    "index.refresh_interval": "1s",
    "index.max_result_window": "1000000",
    "index.number_of_replicas": "1"
}
```
