To do this, you can use Suspense to suspend on the data, and `prerender` will wait for the suspended content to finish before resolving to the static HTML.

 In this example, the `SearchResults` component [suspends](/reference/react/Suspense#displaying-a-fallback-while-content-is-loading) while fetching the search results. Try typing `"a"`, waiting for the results, and then editing it to `"ab"`. The results for `"a"` get replaced by the loading fallback.
