How can I customize the kbar search?

Add a SearchProvider component such as the one shown below and use it in place of the default SearchProvider component in app/layout.tsx.

defaultActions are the initial list of actions.

onSearchDocumentsLoad is a callback function that is called when the documents specified by searchDocumentsPath are loaded. Set searchDocumentsPath to false to disable the dynamically loaded search feature.

'use client'

import { KBarSearchProvider } from 'pliny/search/KBar'
import { useRouter } from 'next/navigation'
import { CoreContent } from 'pliny/utils/contentlayer'
import { Blog } from 'contentlayer/generated'

export const SearchProvider = ({ children }) => {
  const router = useRouter()
  return (
    <KBarSearchProvider
      kbarConfig={{
        searchDocumentsPath: 'search.json',
        defaultActions: [
          {
            id: 'homepage',
            name: 'Homepage',
            keywords: '',
            shortcut: ['h', 'h'],
            section: 'Home',
            perform: () => router.push('/'),
          },
          {
            id: 'projects',
            name: 'Projects',
            keywords: '',
            shortcut: ['p'],
            section: 'Home',
            perform: () => router.push('/projects'),
          },
        ],
        onSearchDocumentsLoad(json) {
          return json.map((post: CoreContent<Blog>) => ({
            id: post.path,
            name: post.title,
            keywords: post?.summary || '',
            section: 'Blog',
            subtitle: post.tags.join(', '),
            perform: () => router.push('/' + post.path),
          }))
        },
      }}
    >
      {children}
    </KBarSearchProvider>
  )
}

You can even choose to do a full text search over the entire generated blog content though this would come at the expense of a larger search index file by modifying the createSearchIndex function in contentlayer.config.ts to:

function createSearchIndex(allBlogs) {
  if (
    siteMetadata?.search?.provider === 'kbar' &&
    siteMetadata.search.kbarConfig.searchDocumentsPath
  ) {
    writeFileSync(
      `public/${siteMetadata.search.kbarConfig.searchDocumentsPath}`,
      JSON.stringify(sortPosts(allBlogs))
    )
    console.log('Local search index generated...')
  }
}

Note the change from JSON.stringify(allCoreContent(sortPosts(allBlogs))) to JSON.stringify((sortPosts(allBlogs))).

Next, in the modified SearchProvider, dump the raw content to the keywords field in the onSearchDocumentsLoad prop:

onSearchDocumentsLoad(json) {
  return json.map((post: Blog) => ({
    id: post.path,
    name: post.title,
    keywords: post.body.raw,
    section: 'Blog',
    subtitle: post.tags.join(', '),
    perform: () => router.push('/' + post.path),
  }))
}
