# “替换为”可以使用正则表达式吗？

是的！要使用正则表达式执行“替换”操作（可在以下 *查找 > 替换* 菜单项），你可以按如下方式指定字段：

```
替换：/([a-z])-([a-z])/
使用：/$1$2/
```

其中 $1、$2 等是对第一个、第二个捕获组的反向引用。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://overleaf-pro.ayaka.space/latex/zh-cn/zhi-shi-ku/019-can-i-use-regular-expressions-for-replace-with.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
