如何使用建议在 django 中制作搜索引擎？

Question

I want to make a search bar that works with JavaScript. That way, I can add suggestions like Google does when you are looking for something. I already have the search bar and the view to filter the Patient s (my model).

Here is the code

def search_patient(request):
  """
  Will return all the patients that start with the name that the user searches
  """
  q = request.POST['q']
  results = Patient.objects.filter(names__startswith=q)
  for result in results:
    result.serialize()

  return JsonResponse({'results': results}, status=200)

It is a pretty simple function. The problem is that I really think that requesting the new string every time the user types a letter or deletes one would blow up the server, and I don't want that. I really need help here, and I am open to every suggestion.

Thanks!

You can put minimum character length on your javascript before the suggestion functionality triggered.
