search not working on vercel with remote content

[Codeize]

To Reproduce

1. Follow the guide on remote content using GitHub: https://fumadocs.vercel.app/docs/headless/remote/github
2. Deploy to production on Vercel

Current vs. Expected behavior

Even whilst running the app in production mode locally, it builds the search index as I expect it to, and then the search functionality itself works as I expect it to.

However, when deploying onto Vercel - according to the build logs - it builds the search index correctly, however when searching for the same content as I did locally it returns no results.

Which area(s) are affected? (Select all that apply)

Core, MDX

Additional context

I have altered the setup to remove /docs being the root, and instead / being the root, as for our use case the docs would be hosted as a separate website to the main website. Albeit unlikely, maybe this has broken something?

How do you setup search API? Are you using 3rd party solutions like Algolia Search, or using your own implementation?

[Codeize]

I am just using the out-of-the-box solution provided by the remote MDX example, createSearchAPI:

• https://github.com/fuma-nama/fumadocs/blob/dev/examples/remote-mdx/app/api/search/route.ts

[fuma-nama]

Don't use that example in production, it's not compatible with serverless runtime. It's just for experimental purposes. As we recommended, use 3rd party solutions like Algolia Search.

Otherwise, using the Fumadocs built-in search, it requires a redeployment when your content changes, which wasted the optimisation of MDX remote.

Alright, thank you.
