you can set them by redirecting the client to it. And yes you need a client, because a server actions runs on the server and the server don't know states. So return for example the redirect url (with the searchparams) and after your server actions is complete redirect the client to the new url @Chausie

That makes sense, didn't think of it. Thanks! Any idea why I do not get type inference searchParams object from the props?

no idea without seeing the code

usually in previous projects I got searchParams sugguested by the next envoirment, but now in this one not.

export default function Home({ searchParams }: any) {
 //...
}

I do not really know what type it is.

try it like this:

export default function Home({
  searchParams,
}: {
  searchParams: { [key: string]: string | string[] | undefined }
}) {
 // ...
}
