step1: Install plugin and dependencies
pnpm add vitepress-plugin-pagefind pagefind
# or
npm i vitepress-plugin-pagefind pagefind
# or
yarn add vitepress-plugin-pagefind pagefindstep2: import plugin
in .vitepress/config.ts
import { defineConfig } from 'vitepress'
import { pagefindPlugin } from 'vitepress-plugin-pagefind'
// https://vitepress.dev/reference/site-config
export default defineConfig({
vite: {
plugins: [pagefindPlugin()],
}
})or in vite.config.ts
// vite.config.ts
import { pagefindPlugin } from 'vitepress-plugin-pagefind'
import { defineConfig } from 'vite'
export default defineConfig({
plugins: [pagefindPlugin()],
})step3: Chinese search optimization
if your docs language（lang） is Chinese (zh-)
in .vitepress/config.ts，recommend import chineseSearchOptimize fun
import { defineConfig } from 'vitepress'
import { chineseSearchOptimize, pagefindPlugin } from 'vitepress-plugin-pagefind'
export default defineConfig({
lang: 'zh-cn',
vite: {
plugins: [pagefindPlugin({
customSearchQuery: chineseSearchOptimize
})],
},
})see Example4 below for details
pagefindPlugin({
btnPlaceholder: '搜索',
placeholder: '搜索文档',
emptyText: '空空如也',
heading: '共: {{searchResult}} 条结果',
// toSelect: '',
// toNavigate: '',
// toClose: '',
// searchBy: '',
})The main goal is to exclude public content from each article
pagefindPlugin({
excludeSelector: ['img', 'a.header-anchor']
})Different languages have different strategies for generating content index，more detail see pagefind：multilingual
pagefindPlugin({
forceLanguage: 'zh-cn'
})recommend：default use vitepress siteConfig lang
import { defineConfig } from 'vitepress'
export default defineConfig({
title: 'My Awesome Project',
description: 'A VitePress Site',
// ...other config
lang: 'zh-cn',
// ^^^^^^^^^
})You can see the language used in the final build message.
like this below
pagefind 目前对中文支持还不如英语完善，下面是官方的介绍
问题主要是自动分词这一块，咱们可以在搜索词的时候做一下优化，比如自动把搜索输入的内容拆成1个个的单字
pagefindPlugin({
customSearchQuery(input) {
// 将搜索的每个中文单字两侧加上空格
return input.replace(/[\u4E00-\u9FA5]/g, ' $& ')
.replace(/\s+/g, ' ')
.trim()
}
})| 调整前 | 调整后 |

If you have a better implementation, welcome to share
Use the filter method to customize the filtering behavior.
pagefindPlugin({
filter(searchItem, idx, originArray) {
console.log(searchItem)
return !searchItem.route.includes('404')
}
})set frontmatter pagefind-indexed: false to exclude.
---
pagefind-indexed: false
---pagefind search results will only contain content in the same language as the current page (distinguished by the lang attribute of the page)
Here is an example of how to configure the search box to display different text in different language pages
.vitepress/config.ts
export default defineConfig({
// ...other config
locales: {
root: {
lang: 'en',
label: 'English'
},
zh: {
lang: 'zh-cn',
label: '简体中文',
}
},
vite: {
plugins: [pagefindPlugin(
{
locales: {
root: {
btnPlaceholder: 'Search',
placeholder: 'Search Docs...',
emptyText: 'No results',
heading: 'Total: {{searchResult}} search results.',
},
zh: {
btnPlaceholder: '搜索',
placeholder: '搜索文档',
emptyText: '空空如也',
heading: '共: {{searchResult}} 条结果',
// 搜索结果不展示最后修改日期日期
showDate: false
}
}
}
)],
}
})| English | 简体中文 |

You may need this if you are using a lower version or another version of pagefind; You can also use this to customize some CLI configurations when the default configuration is not satisfied
CLI Options See： https://pagefind.app/docs/config-options/
# use pagefind 0.12.0
pnpm add [email protected]pagefindPlugin({
indexingCommand: 'npx pagefind --source "docs/.vitepress/dist" --bundle-dir "pagefind" --exclude-selectors "div.aside, a.header-anchor"'
})If the plugin cannot execute normally in the buildEnd stage, or custom indexing file location.
pagefindPlugin({
manual: true
})① modify script
add pagefind indexing generation script
CLI Options See： https://pagefind.app/docs/config-options/
{
"scripts": {
"docs:build": "vitepress build docs && npx pagefind --site docs/.vitepress/dist --exclude-selectors div.aside,a.header-anchor"
}
}② add head script
import { defineConfig } from 'vitepress'
import { pagefindPlugin } from 'vitepress-plugin-pagefind'
export default defineConfig({
head: [
// add script，manually specify the location of the import index file
[
'script',
{},
`import('/pagefind/pagefind.js')
.then((module) => {
window.__pagefind__ = module
module.init()
})
.catch(() => {
// console.log('not load /pagefind/pagefind.js')
})`
]
],
vite: {
plugins: [pagefindPlugin({
manual: true
})]
},
lastUpdated: true
})For more configurable options please see the full configuration below
- Filtering of search results
- Sort search results
- Display the last modified date of the article
- Display the last modified date of the article. etc.
