# 更新索引/获取->设置(未完成)

## Update Indices Settings 更新索引设置

实时改变特定索引级别设置。

REST 方式 `/ _settings`(更新所有索引) 或`{index}/_settings`更新一个(或多个)索引设置。请求的主体包括更新设置,例如:

```
{
    "index" : {
        "number_of_replicas" : 4
    }
}
```

将副本的数量设置为4个。下面是一个curl的例子:

```
curl -XPUT 'localhost:9200/my_index/_settings' -d '
{
    "index" : {
        "number_of_replicas" : 4
    }
}'
```

可以在动态索引上动态更新的每个索引设置列表可以在索引模块([Index Modules](https://www.elastic.co/guide/en/elasticsearch/reference/5.2/index-modules.html))中找到。

### 批量索引的使用

在开始批量索引之前，使用：

```
curl -XPUT localhost:9200/test/_settings -d '{
    "index" : {
        "refresh_interval" : "-1"
    } }'
```
