My musings on Office 365, search, programming and technology. (June 1st, 2019, I started as a full time employee of Microsoft, thus any post before that date are solely written on my own behalf)
If you want to paginate over a large set of results for some reason using the Microsoft Graph Search API, you can employ the logic mentioned for the SharePoint API at https://learn.microsoft.com/en-us/sharepoint/dev/general-development/pagination-for-large-result-sets . Note that this option applies to OneDrive and SharePoint items, not necessarily other content sources available via the Graph Search API (not tested).
Use a basic JSON template like below for your search requests, or modify to add other parameters needed for your request.
