Search

Local Search

VitePress supports fuzzy full-text search using a in-browser index thanks to minisearch. To enable this feature, simply set the themeConfig.search.provider option to 'local' in your .vitepress/config.ts file:

import { defineConfig } from 'vitepress'

export default defineConfig({
  themeConfig: {
    search: {
      provider: 'local'
    }
  }
})

Example result:

Alternatively, you can use Algolia DocSearch or some community plugins like https://www.npmjs.com/package/vitepress-plugin-search or https://www.npmjs.com/package/vitepress-plugin-pagefind.

i18n

You can use a config like this to use multilingual search:

import { defineConfig } from 'vitepress'

export default defineConfig({
  themeConfig: {
    search: {
      provider: 'local',
      options: {
        locales: {
          zh: { // make this `root` if you want to translate the default locale
            translations: {
              button: {
                buttonText: '搜索',
                buttonAriaLabel: '搜索'
              },
              modal: {
                displayDetails: '显示详细列表',
                resetButtonTitle: '重置搜索',
                backButtonTitle: '关闭搜索',
                noResultsText: '没有结果',
                footer: {
                  selectText: '选择',
                  selectKeyAriaLabel: '输入',
                  navigateText: '导航',
                  navigateUpKeyAriaLabel: '上箭头',
                  navigateDownKeyAriaLabel: '下箭头',
                  closeText: '关闭',
                  closeKeyAriaLabel: 'esc'
                }
              }
            }
          }
        }
      }
    }
  }
})

miniSearch options

You can configure MiniSearch like this:

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: {
            /* ... */
          }
        }
      }
    }
  }
})

Custom content renderer

You can customize the function used to render the markdown content before indexing it:

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) {
          // return html string
        }
      }
    }
  }
})

This function will be stripped from client-side site data, so you can use Node.js APIs in it.

Example: Excluding pages from search

You can exclude pages from search by adding search: false to the frontmatter of the page. Alternatively:

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 Note In case a custom _render function is provided, you need to handle the search: false frontmatter yourself. Also, the env object won't be completely populated before md.render is called, so any checks on optional env properties like frontmatter should be done after that. :::

Example: Transforming content - adding anchors

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

VitePress supports searching your docs site using Algolia DocSearch. Refer their getting started guide. In your .vitepress/config.ts you'll need to provide at least the following to make it work:

import { defineConfig } from 'vitepress'

export default defineConfig({
  themeConfig: {
    search: {
      provider: 'algolia',
      options: {
        appId: '...',
        apiKey: '...',
        indexName: '...'
      }
    }
  }
})

i18n

You can use a config like this to use multilingual search:

import { defineConfig } from 'vitepress'

export default defineConfig({
  themeConfig: {
    search: {
      provider: 'algolia',
      options: {
        appId: '...',
        apiKey: '...',
        indexName: '...',
        locales: {
          zh: {
            placeholder: '搜索文档',
            translations: {
              button: {
                buttonText: '搜索文档',
                buttonAriaLabel: '搜索文档'
              },
              modal: {
                searchBox: {
                  resetButtonTitle: '清除查询条件',
                  resetButtonAriaLabel: '清除查询条件',
                  cancelButtonText: '取消',
                  cancelButtonAriaLabel: '取消'
                },
                startScreen: {
                  recentSearchesTitle: '搜索历史',
                  noRecentSearchesText: '没有搜索历史',
                  saveRecentSearchButtonTitle: '保存至搜索历史',
                  removeRecentSearchButtonTitle: '从搜索历史中移除',
                  favoriteSearchesTitle: '收藏',
                  removeFavoriteSearchButtonTitle: '从收藏中移除'
                },
                errorScreen: {
                  titleText: '无法获取结果',
                  helpText: '你可能需要检查你的网络连接'
                },
                footer: {
                  selectText: '选择',
                  navigateText: '切换',
                  closeText: '关闭',
                  searchByText: '搜索提供者'
                },
                noResultsScreen: {
                  noResultsText: '无法找到相关结果',
                  suggestedQueryText: '你可以尝试查询',
                  reportMissingResultsText: '你认为该查询应该有结果？',
                  reportMissingResultsLinkText: '点击反馈'
                }
              }
            }
          }
        }
      }
    }
  }
})

These options can be overridden. Refer official Algolia docs to learn more about them.
