Have you ever visited a website and struggled to find what you needed? A good search function helps people find information quickly. In this post, I'll show you how to add a powerful local search feature to your Docusaurus site that works offline and requires no external services.

What You'll Need​

1. A Docusaurus project (version 2.0 or later)
2. Node.js and npm installed

Install the Local Search Plugin​

First, install the local search plugin by running this command in your terminal:

npm install @easyops-cn/docusaurus-search-local

Update Your Docusaurus Configuration​

Open your docusaurus.config.js file and add the local search plugin to your plugins array:

plugins: [
  // ... other plugins
  [
    require.resolve('@easyops-cn/docusaurus-search-local'),
    {
      hashed: true,
      indexDocs: true,
      indexBlog: true,
      indexPages: true,
      docsRouteBasePath: '/docs',
      blogRouteBasePath: '/blog',
    },
  ],
],

Add the Search Bar to Your Navbar​

In your docusaurus.config.js, add the search bar to your navbar items:

items: [
  // ... other items
  {
    type: 'search',
    position: 'right',
  },
]

Build and Test Your Site​

Build your Docusaurus site to generate the search index:

npm run build

Then serve the built files to test the search:

npm run serve

Visit http://localhost:3000 and you should see a search icon in the navbar. The first time you click it, it will build the search index (this might take a few seconds). After that, you can search across all your documentation and blog posts.

Benefits of Local Search​

• Works offline after the first load
• No external dependencies or API keys required
• Fast and responsive
• Indexes all your content during build time
• Supports fuzzy search for better results

Troubleshooting​

• If the search doesn't work, try clearing your browser cache
• Make sure you've built your site after adding the search plugin
• Check your browser's console for any error messages
• Ensure all the routes you want to index are correctly specified in the plugin configuration

Conclusion​

Adding local search to your Docusaurus site is a great way to improve user experience without relying on external services. The setup is simple, and the performance is excellent since everything runs in the browser.
