How to filter by unknown parameters in Django?

Question

Django

I have several parameters with values ​​that can be selected for filtering.
The fact is that the admin can add other parameters and their values ​​must also go into the get request and be processed on the server.
It looks something like this:

Country
*checkbox* USA
*checkbox* Germany

Resolution
*checkbox* 1920x1080
*checkbox* 5120x...

Other parameters
....

So I have several filters there and it will look something like:
products = Product.objects. filter(Q(country=request.GET.get('country') || Q(resolution=request.GET.get('resolution')) and so on

But how to make the parameters by which to filter become dynamic?
