Search index is skipping files

I can't reopen #265 but the search indexing issue doesn't seem to be resolved in the latest release (v1.0.11).

Steps to reproduce:
- Clone https://github.com/ensdomains/docs/tree/vocs
- `pnpm install && pnpm build`
- `pnpm preview`
- Search "deployments", notice it doesn't return the `/learn/deployments` page
