# 搜索 {#search}
|
|
|
|
|
|
|
|
|
|
## 本地搜索 {#local-search}
|
|
|
|
|
|
|
|
|
|
得益于 [minisearch](https://github.com/lucaong/minisearch/),VitePress 支持使用浏览器内索引进行模糊全文搜索。要启用此功能,只需在 `.vitepress/config.ts` 文件中将 `themeConfig.search.provider` 选项设置为 `'local'` 即可:
|
|
|
|
|
|
|
|
|
|
```ts
|
|
|
|
|
import { defineConfig } from 'vitepress'
|
|
|
|
|
|
|
|
|
|
export default defineConfig({
|
|
|
|
|
themeConfig: {
|
|
|
|
|
search: {
|
|
|
|
|
provider: 'local'
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
})
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
示例结果:

或者,你可以使用 [Algolia DocSearch](#algolia-search) 或一些社区插件,例如:<https://www.npmjs.com/package/vitepress-plugin-search> 或者 <https://www.npmjs.com/package/vitepress-plugin-pagefind>。

### i18n {#local-search-i18n}
|
|
|
|
|
|
|
|
|
|
你可以使用这样的配置来使用多语言搜索:
|
|
|
|
|
|
|
|
|
|
```ts
|
|
|
|
|
import { defineConfig } from 'vitepress'
|
|
|
|
|
|
|
|
|
|
export default defineConfig({
|
|

}
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
})
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
### MiniSearch 配置项 {#mini-search-options}
|
|
|
|
|
|
|
|
|
|
你可以像这样配置 MiniSearch :
|
|
|
|
|
|
|
|
|
|
```ts
|
|
|
|
|
import { defineConfig } from 'vitepress'
|
|
|
|
|
|
|
|
|
|
export default defineConfig({
|
|
|
|
|
themeConfig: {
|
|
|
|
|
search: {
|
|
|
|
|
provider: 'local',
|
|
|
|
|
options: {
|
|
|
|
|
miniSearch: {
|
|
|
|
|
/**
|
|
|
|
|
* @type {Pick<import('minisearch').Options, 'extractField' | 'tokenize' | 'processTerm'>}
|
|
|
|
|
*/
|
|
|
|
|
options: {
|
|
|
|
|
/* ... */
|
|
|
|
|
},
|
|
|
|
|
/**
|
|
|
|
|
* @type {import('minisearch').SearchOptions}
|
|
|
|
|
* @default
|
|
|
|
|
* { fuzzy: 0.2, prefix: true, boost: { title: 4, text: 2, titles: 1 } }
|
|
|
|
|
*/
|
|
|
|
|
searchOptions: {
|
|
|
|
|
/* ... */
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
})
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|

### 自定义渲染内容 {#custom-content-renderer}
|
|
|
|
|
|
|
|
|
|
可以在索引之前自定义用于渲染 Markdown 内容的函数:
|
|
|
|
|
|
|
|
|
|
```ts
|
|
|
|
|
import { defineConfig } from 'vitepress'
|
|
|
|
|
|
|
|
|
|
export default defineConfig({
|
|
|
|
|
themeConfig: {
|
|
|
|
|
search: {
|
|
|
|
|
provider: 'local',
|
|
|
|
|
options: {
|
|
|
|
|
/**
|
|
|
|
|
* @param {string} src
|
|
|
|
|
* @param {import('vitepress').MarkdownEnv} env
|
|
|
|
|
* @param {import('markdown-it')} md
|
|
|
|
|
*/
|
|
|
|
|
_render(src, env, md) {
|
|
|
|
|
// 返回 html 字符串
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
})
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
该函数将从客户端站点数据中剥离,因此你可以在其中使用 Node.js API。
|
|
|
|
|
|
|
|
|
|
#### 示例:从搜索中排除页面 {#example-excluding-pages-from-search}
|
|
|
|
|
|
|
|
|
|
你可以通过将 `search: false` 添加到页面的 `frontmatter` 来从搜索中排除页面。或者:
|
|
|
|
|
|
|
|
|
|
```ts
|
|
|
|
|
import { defineConfig } from 'vitepress'
|
|
|
|
|
|
|
|
|
|
export default defineConfig({
|
|
|
|
|
themeConfig: {
|
|
|
|
|
search: {
|
|
|
|
|
provider: 'local',
|
|
|
|
|
options: {
|
|
|
|
|
_render(src, env, md) {
|
|
|
|
|
const html = md.render(src, env)
|
|
|
|
|
if (env.frontmatter?.search === false) return ''
|
|
|
|
|
if (env.relativePath.startsWith('some/path')) return ''
|
|
|
|
|
return html
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
})
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
::: warning 注意
|
|
|
|
|
如果提供了自定义的 `_render` 函数,你需要自己处理 `search: false` 的 frontmatter。此外,在调用 `md.render` 之前,`env` 对象不会完全填充,因此对可选 `env` 属性(如 `frontmatter` )的任何检查都应该在此之后完成。
|
|
|
|
|
:::
|
|
|
|
|
|
|
|
|
|
#### 示例:转换内容-添加锚点{#example-transforming-content-adding-anchors}
|
|
|
|
|
|
|
|
|
|
```ts
|
|
|
|
|
import { defineConfig } from 'vitepress'
|
|
|
|
|
|
|
|
|
|
export default defineConfig({
|
|
|
|
|
themeConfig: {
|
|
|
|
|
search: {
|
|
|
|
|
provider: 'local',
|
|
|
|
|
options: {
|
|
|
|
|
_render(src, env, md) {
|
|
|
|
|
const html = md.render(src, env)
|
|
|
|
|
if (env.frontmatter?.title)
|
|
|
|
|
return md.render(`# ${env.frontmatter.title}`) + html
|
|
|
|
|
return html
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
})
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
## Algolia Search {#algolia-search}
|
|
|
|
|
|
|
|
|
|
VitePress 支持使用 [Algolia DocSearch](https://docsearch.algolia.com/docs/what-is-docsearch) 搜索文档站点。请参阅他们的入门指南。在你的 `.vitepress/config.ts` 中,你至少需要提供以下内容才能使其正常工作:
|
|
|
|
|
|
|
|
|
|
```ts
|
|
|
|
|
import { defineConfig } from 'vitepress'
|
|
|
|
|
|
|
|
|
|
export default defineConfig({
|
|
|
|
|
themeConfig: {
|
|
|
|
|
search: {
|
|
|
|
|
provider: 'algolia',
|
|
|
|
|
options: {
|
|
|
|
|
appId: '...',
|
|
|
|
|
apiKey: '...',
|
|
|
|
|
indexName: '...'
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
})
|
|
|
|
|
```
|
|
|
|

|
|
|
|
|
### i18n {#algolia-search-i18n}
