搜索 | 智流GEO - 品牌 AI 搜索可见度分析平台

Fumadocs UI provides a good-looking search UI for your docs, the search functionality is instead provided and documented on Fumadocs Core.

See Document Search.

Search UI

Open with Cmd K or Ctrl K.

Configurations

You can customize search UI from the Root Provider component in root layout.

When not specified, it uses the Default fetch Search Client powered by Orama.

Custom Links

Add custom link items to search dialog. They are shown as fallbacks when the query is empty.

app/layout.tsx

import { RootProvider } from 'fumadocs-ui/root-provider';

<RootProvider
  search={{
    links: [
      ['Home', '/'],
      ['Docs', '/docs'],
    ],
  }}
>
  {children}
</RootProvider>;

Disable Search

To opt-out of document search, disable it from root provider.

import { RootProvider } from 'fumadocs-ui/root-provider';

<RootProvider
  search={{
    enabled: false,
  }}
>
  {children}
</RootProvider>;

Hot Keys

Customise the hot keys to trigger search dialog.

import { RootProvider } from 'fumadocs-ui/root-provider';

<RootProvider
  search={{
    hotKey: [
      {
        display: 'K',
        key: 'k', // key code, or a function determining whether the key is pressed
      },
    ],
  }}
>
  {children}
</RootProvider>;

Tag Filter

Add UI to change filters. Make sure to configure Tag Filter on search server first.

import { RootProvider } from 'fumadocs-ui/root-provider';

<RootProvider
  search={{
    options: {
      defaultTag: 'value',
      tags: [
        {
          name: 'Tag Name',
          value: 'value',
        },
      ],
    },
  }}
>
  {children}
</RootProvider>;

Search Options

Pass options to the search client, like changing the API endpoint for Orama search server:

import { RootProvider } from 'fumadocs-ui/root-provider';

<RootProvider
  search={{
    options: {
      api: '/api/search/docs',
    },
  }}
>
  {children}
</RootProvider>;

Replace Search Dialog

You can replace the default Search Dialog with:

components/search.tsx

'use client';
import SearchDialog from 'fumadocs-ui/components/dialog/search-default';
import type { SharedProps } from 'fumadocs-ui/components/dialog/search';

export default function CustomDialog(props: SharedProps) {
  // your own logic here
  return <SearchDialog {...props} />;
}

To pass it to the Root Provider, you need a wrapper with use client directive.

provider.tsx

'use client';
import { RootProvider } from 'fumadocs-ui/provider';
import dynamic from 'next/dynamic';
import type { ReactNode } from 'react';

const SearchDialog = dynamic(() => import('@/components/search')); // lazy load

export function Provider({ children }: { children: ReactNode }) {
  return (
    <RootProvider
      search={{
        SearchDialog,
      }}
    >
      {children}
    </RootProvider>
  );
}

Use it instead of your previous Root Provider

layout.tsx

import { Provider } from './provider';
import type { ReactNode } from 'react';

export default function Layout({ children }: { children: ReactNode }) {
  return (
    <html lang="en">
      <body>
        <Provider>{children}</Provider>
      </body>
    </html>
  );
}

Built-in UI

If you want to use the built-in search dialog UI instead of building your own, you may use the SearchDialog component.

import {
  SearchDialog,
  type SharedProps,
} from 'fumadocs-ui/components/dialog/search';

export default function CustomSearchDialog(props: SharedProps) {
  return <SearchDialog {...props} />;
}

Unstable

It is an internal API, might break during iterations
