FlexSearch

Overview

For the setup guide, see Integrate FlexSearch.

It searches through an API endpoint running on the server, or through a statically cached JSON file for static sites.

Setup

Create a search dialog.

components/search.tsx

'use client';
import { useFetchSearch } from 'fumadocs-core/search/client';
import {
  SearchDialog,
  SearchDialogClose,
  SearchDialogContent,
  SearchDialogHeader,
  SearchDialogIcon,
  SearchDialogInput,
  SearchDialogList,
  SearchDialogOverlay,
  type SharedProps,
} from 'fumadocs-ui/components/dialog/search';
import { useI18n } from 'fumadocs-ui/contexts/i18n';

export default function DefaultSearchDialog(props: SharedProps) {
  const { locale } = useI18n(); // (optional) for i18n
  const search = useFetchSearch({
    locale,
  });

  return (
    <SearchDialog {...search} {...props}>
      <SearchDialogOverlay />
      <SearchDialogContent>
        <SearchDialogHeader>
          <SearchDialogIcon />
          <SearchDialogInput />
          <SearchDialogClose />
        </SearchDialogHeader>
        <SearchDialogList />
      </SearchDialogContent>
    </SearchDialog>
  );
}

Replace Search Dialog

Your provider component already passes src/components/search.tsx to <RootProvider />, so replacing that file is enough:

src/components/provider.tsx

import { navigate } from 'astro:transitions/client';
import type { ReactNode } from 'react';
import { RootProvider } from 'fumadocs-ui/provider/astro';
import SearchDialog from '@/components/search';

export interface ProviderProps {
  pathname: string;
  params: Record<string, string | undefined>;
  children?: ReactNode;
}

export function Provider({ pathname, params, children }: ProviderProps) {
  return (
    <RootProvider
      pathname={pathname}
      params={params}
      navigate={navigate}
      search={{ SearchDialog }}
    >
      {children}
    </RootProvider>
  );
}

Tag Filter

Optionally, you can add UI for filtering results by tags. Configure Tag Filter on search server and add the following:

'use client';

import {
  SearchDialog,
  SearchDialogContent,
  SearchDialogFooter,
  SearchDialogOverlay,
  type SharedProps,
  TagsList,
  TagsListItem,
} from 'fumadocs-ui/components/dialog/search';
import { useState } from 'react';
import { useFlexsearchStatic } from 'fumadocs-core/search/client/flexsearch-static';

export default function CustomSearchDialog(props: SharedProps) {
  const [tag, setTag] = useState<string | undefined>();
  const search = useFlexsearchStatic({
    tag, 
  });

  return (
    <SearchDialog {...search} {...props}>
      <SearchDialogOverlay />
      <SearchDialogContent>
        ...
        <SearchDialogFooter className="flex flex-row">
          <TagsList tag={tag} onTagChange={setTag}>
            <TagsListItem value="my-value">My Value</TagsListItem>
          </TagsList>
        </SearchDialogFooter>
      </SearchDialogContent>
    </SearchDialog>
  );
}
