配置algolia

1、注册账号

首先需要去 algolia 官网注册自己的账号，可以直接使用 Github 或者其他邮箱注册登录。

新账号会自动创建一个Application ，也可以自己创建一个新的

点击确定后接着下一个页面继续点击create Application按钮，然后点击NEXT就创建了一个新的Application，创建完成后点击 Skip for now，不然会根据域名生成index名称，爬虫配置也不对

2、新建index

按下图步骤创建index

3、验证域名

按要求验证域名

然后点击Skip for now进行下一步骤

4、配置爬虫

按下图所示新建爬虫

新建后点击爬虫名称进入爬虫配置

爬虫配置如下，将域名和indexName改成自己配置的，配置完成后点击右上角start Crawling开始爬取网站内容

1、只爬取正文

5、索引设置

回到搜索页面看是否有数据

接着配置索引，选择要搜索的内容

接着配置facets，这是实现高级搜索和筛选功能的核心特性之一，主要作用是帮助用户快速缩小搜索范围，提升搜索体验，这里要重点注意 lang必须被选择，否则网页搜索为空

6、代码配置

按图所示找到下面的配置

export default defineConfig({
   ...
    lang: "zh-CN",
   ...
    themeConfig: ({
      ...
        search: {
            provider: 'algolia',
            options: {
                appId: '...',
                apiKey: '...',
                indexName: '...'
            },
        } 
      ...
    })
})

配置algolia ​

1、注册账号 ​

2、新建index ​

3、验证域名 ​

4、配置爬虫 ​

1、只爬取正文 ​

2、同时爬取代码块 ​

正文和代码块分开 ​

正文和代码块合并 ​

5、索引设置 ​

6、代码配置 ​
