搜索

有几种为你的网站添加搜索功能的方案：

🥇 Algolia DocSearch (official)
👥 Typesense DocSearch
👥 Local Search
👥 Your own SearchBar component

信息

🥇 Docusaurus provides first-class support for Algolia DocSearch.

👥 Other options are maintained by the community: please report bugs to their respective repositories.

🥇 Using Algolia DocSearch

Docusaurus has official support for Algolia DocSearch.

The service is free for any developer documentation or technical blog: just make sure to read the checklist and apply to the DocSearch program.

Docsearch 每周一次爬取你的网站（可以在网页界面上配置具体时间），并将所有内容汇总到一个 Algolia 索引中。随后，你的前端会调用 Algolia API 来直接查询这些内容。

If your website is not eligible for the free, hosted version of DocSearch, or if your website sits behind a firewall and is not public, then you can run your own DocSearch crawler.

备注

By default, the Docusaurus preset generates a sitemap.xml that the Algolia crawler can use.

From the old docsearch?

You can read more about migration from the legacy DocSearch infra in our blog post or the DocSearch migration docs.

Index Configuration

在你的申请被批准并部署完毕后，你会收到一封包含所有详细信息的电子邮件，告诉你如何将 DocSearch 添加到你的项目。 Editing and managing your crawls can be done via the web interface. 部署完毕后，索引就立即可用了，所以一般不需要手动配置。

Use the recommended crawler config

It is highly recommended to use our official Docusaurus v3 crawler configuration. We cannot support you if you choose a different crawler configuration.

When updating your crawler config

The crawler configuration contains a initialIndexSettings, which will only be used to initialize your Algolia index if it does not exist yet.

If you update your initialIndexSettings crawler setting, it is possible to update the index manually through the interface, but the Algolia team recommends to delete your index and then restart a crawl to fully reinitialize it with the new settings.

Connecting Algolia

Docusaurus' own @docusaurus/preset-classic supports Algolia DocSearch integration. 如果你用的是经典预设，就不需要额外安装任何东西。

Installation steps when not using @docusaurus/preset-classic

安装软件包：

npm
Yarn
pnpm

npm install --save @docusaurus/theme-search-algolia

yarn add @docusaurus/theme-search-algolia

pnpm add @docusaurus/theme-search-algolia

docusaurus.config.js
export default {
  title: 'My site',
  // ...
  themes: ['@docusaurus/theme-search-algolia'],
  themeConfig: {
    // ...
  },
};

Then, add an algolia field in your themeConfig. Apply for DocSearch to get your Algolia index and API key.

docusaurus.config.js
export default {
  // ...
  themeConfig: {
    // ...
    algolia: {
      // The application ID provided by Algolia
      appId: 'YOUR_APP_ID',

      // Public API key: it is safe to commit it
      apiKey: 'YOUR_SEARCH_API_KEY',

      indexName: 'YOUR_INDEX_NAME',

      // Optional: see doc section below
      contextualSearch: true,

      // Optional: Specify domains where the navigation should occur through window.location instead on history.push. Useful when our Algolia config crawls multiple documentation sites and we want to navigate with window.location.href to them.
      externalUrlRegex: 'external\\.com|domain\\.com',

      // Optional: Replace parts of the item URLs from Algolia. Useful when using the same search index for multiple deployments using a different baseUrl. You can use regexp or string in the `from` param. For example: localhost:3000 vs myCompany.com/docs
      replaceSearchResultPathname: {
        from: '/docs/', // or as RegExp: /\/docs\//
        to: '/',
      },

      // Optional: Algolia search parameters
      searchParameters: {},

      // Optional: path for search page that enabled by default (`false` to disable it)
      searchPagePath: 'search',

      // Optional: whether the insights feature is enabled or not on Docsearch (`false` by default)
      insights: false,

      //... other Algolia params
    },
  },
};

信息

The searchParameters option used to be named algoliaOptions in Docusaurus v1.

Refer to its official DocSearch documentation for possible values.

warning

在 Algolia 爬取你的网站之前，搜索功能无法可靠地工作。

If search doesn't work after any significant change, please use the Algolia dashboard to trigger a new crawl.

Contextual search

Contextual search is enabled by default.

It ensures that search results are relevant to the current language and version.

docusaurus.config.js
export default {
  // ...
  themeConfig: {
    // ...
    algolia: {
      contextualSearch: true,
    },
  },
};

Let's consider you have 2 docs versions (v1 and v2) and 2 languages (en and fr).

浏览 v2 的文档时，返回 v1 文档的搜索结果会很奇怪。有时侯 v1 和 v2 的文档非常相似，导致同一个查询产生重复的搜索结果（每个版本一个结果）。

同样，在浏览中文网站时，返回英文文档的搜索结果也很奇怪。

上下文搜索功能解决了这个问题。它能够理解你正在浏览某个文档版本及语言，并动态创建搜索过滤器。

on /en/docs/v1/myDoc, search results will only include English results for the v1 docs (+ other unversioned pages)
on /fr/docs/v2/myDoc, search results will only include French results for the v2 docs (+ other unversioned pages)

信息

When using contextualSearch: true (default), the contextual facet filters will be merged with the ones provided with algolia.searchParameters.facetFilters .

For specific needs, you can disable contextualSearch and define your own facetFilters:

docusaurus.config.js
export default {
  // ...
  themeConfig: {
    // ...
    algolia: {
      contextualSearch: false,
      searchParameters: {
        facetFilters: ['language:en', ['filter1', 'filter2'], 'filter3'],
      },
    },
  },
};

Refer to the relevant Algolia faceting documentation.

Contextual search doesn't work?

If you only get search results when Contextual Search is disabled, this is very likely because of an index configuration issue.

Styling your Algolia search

DocSearch 默认自带一个精心设计的主题，保证可访问性，确保颜色和对比度符合标准。

Still, you can reuse the Infima CSS variables from Docusaurus to style DocSearch by editing the /src/css/custom.css file.

/src/css/custom.css
[data-theme='light'] .DocSearch {
  /* --docsearch-primary-color: var(--ifm-color-primary); */
  /* --docsearch-text-color: var(--ifm-font-color-base); */
  --docsearch-muted-color: var(--ifm-color-secondary-darkest);
  --docsearch-container-background: rgba(94, 100, 112, 0.7);
  /* 弹窗 */
  --docsearch-modal-background: var(--ifm-color-secondary-lighter);
  /* 搜索框 */
  --docsearch-searchbox-background: var(--ifm-color-secondary);
  --docsearch-searchbox-focus-background: var(--ifm-color-white);
  /* 条目 */
  --docsearch-hit-color: var(--ifm-font-color-base);
  --docsearch-hit-active-color: var(--ifm-color-white);
  --docsearch-hit-background: var(--ifm-color-white);
  /* 页脚 */
  --docsearch-footer-background: var(--ifm-color-white);
}

[data-theme='dark'] .DocSearch {
  --docsearch-text-color: var(--ifm-font-color-base);
  --docsearch-muted-color: var(--ifm-color-secondary-darkest);
  --docsearch-container-background: rgba(47, 55, 69, 0.7);
  /* 弹窗 */
  --docsearch-modal-background: var(--ifm-background-color);
  /* 搜索框 */
  --docsearch-searchbox-background: var(--ifm-background-color);
  --docsearch-searchbox-focus-background: var(--ifm-color-black);
  /* 条目 */
  --docsearch-hit-color: var(--ifm-font-color-base);
  --docsearch-hit-active-color: var(--ifm-color-white);
  --docsearch-hit-background: var(--ifm-color-emphasis-100);
  /* 页脚 */
  --docsearch-footer-background: var(--ifm-background-surface-color);
  --docsearch-key-gradient: linear-gradient(
    -26.5deg,
    var(--ifm-color-emphasis-200) 0%,
    var(--ifm-color-emphasis-100) 100%
  );
}

Customizing the Algolia search behavior

Algolia DocSearch supports a list of options that you can pass to the algolia field in the docusaurus.config.js file.

docusaurus.config.js
export default {
  themeConfig: {
    // ...
    algolia: {
      apiKey: 'YOUR_API_KEY',
      indexName: 'YOUR_INDEX_NAME',
      // Options...
    },
  },
};

Editing the Algolia search component

If you prefer to edit the Algolia search React component, swizzle the SearchBar component in @docusaurus/theme-search-algolia:

npm
Yarn
pnpm

npm run swizzle @docusaurus/theme-search-algolia SearchBar

yarn swizzle @docusaurus/theme-search-algolia SearchBar

pnpm run swizzle @docusaurus/theme-search-algolia SearchBar

Troubleshooting

Here are the most common issues Docusaurus users face when using Algolia DocSearch.

No Search Results

Seeing no search results is usually related to an index configuration problem.

How to check if I have an config problem?

Docusaurus uses Algolia faceting for its Contextual Search feature, to create dynamic queries such as:

[
  "language:en",
  [
    "docusaurus_tag:default",
    "docusaurus_tag:docs-default-3.2.1",
    "docusaurus_tag:docs-community-current",
    "docusaurus_tag:docs-docs-tests-current"
  ]
]

On the Algolia UI, your index should allow to create facet queries on fields docusaurus_tag, language, lang, version, type, as shown in the screenshot below:

Algolia index showing appropriate faceting fields

Alternatively, if you disable Contextual Search with {contextualSearch: false} (which we don't particularly recommend), Docusaurus will not use facet queries, and you should start seeing results.

Use the recommended configuration

We recommend a specific crawler configuration for a good reason. We cannot support you if you choose to use a different configuration.

You can fix index configuration problems by following those steps:

Use the recommend crawler configuration
Delete your index through the UI
Trigger a new crawl through the UI
Check your index is recreated with the appropriate faceting fields: docusaurus_tag, language, lang, version, type
See that you now get search results, even with Contextual Search enabled

Support

Algolia DocSearch 团队可以帮助你解决网站的搜索问题。

You can reach out to Algolia via their support page or on Discord.

Docusaurus also has an #algolia channel on Discord.

👥 Using Typesense DocSearch

Typesense DocSearch works similar to Algolia DocSearch, except that your website is indexed into a Typesense search cluster.

Typesense is an open source instant-search engine that you can either:

Self-Host on your own servers or
Use the Managed Typesense Cloud service.

与 Algolia DocSearch 类似，Typesense 分为两个部分：

typesense-docsearch-scraper - which scrapes your website and indexes the data in your Typesense cluster.
docusaurus-theme-search-typesense - a search bar UI component to add to your website.

Read a step-by-step walk-through of how to run typesense-docsearch-scraper here and how to install the Search Bar in your Docusaurus Site here.

👥 Using Local Search

对于搜索索引比较小的网站，你可以使用本地搜索插件。索引会在用户访问你的网站时下载到浏览器中。

You'll find a list of community-supported local search plugins listed here.

👥 Using your own search

To use your own search, swizzle the SearchBar component in @docusaurus/theme-classic

npm
Yarn
pnpm

npm run swizzle @docusaurus/theme-classic SearchBar

yarn swizzle @docusaurus/theme-classic SearchBar

pnpm run swizzle @docusaurus/theme-classic SearchBar

This will create an src/theme/SearchBar file in your project folder. Restart your dev server and edit the component, you will see that Docusaurus uses your own SearchBar component now.

Notes: You can alternatively swizzle from Algolia SearchBar and create your own search component from there.
