Thanks, @guram-vashakidze, I haven't brought over the unit tests from the parent ES version of the package, and internally I run tests based off: https://github.com/pdphilip/laravel-elasticsearch-tests

For the sake of documentation and for me to append internal tests until I upgrade to GitHub actions, could you share detailed code snippets of the implementation of this?

@pdphilip, As I understood you correct - you asked example of code for usage this new feature:

$index = new OpenSearchModel();
$firstPage = $index
    ->where('foo', 'bar')
    ->orderBy('@timestamp')
    ->orderBy('_id')
    ->limit(10)
    ->get();
$lastSort = $firstPage
    ->last()
    ->getMeta()
    ->sort;
$nextPage = $index
    ->where('foo', 'bar')
    ->orderBy('@timestamp')
    ->orderBy('_id')
    ->searchAfter($lastSort)
    ->limit(10)
    ->get();

In Model's meta i added sort parameter (if it exists in response). The last sort parameter you can use for getting next page by ->searchAfter($lastSort)
