total_results = len(results)
total_pages = (total_results + page_size - 1) // page_size

# Now you can return the total number of pages to your frontend app
# and when the user requests a particular page, you can adjust the
# `PageNumber` parameter in the `paginate` method accordingly to
# retrieve only the results for that page.
