This errors when "search" is not provided in the query string.

What happens is request.args.get("serach") evaluates to None, and then since None has no replace method an AttributeError gets raised.

Testing from the frontend, this happens when the search bar is empty.

Need to account for the case where "search" is not passed as a query parameter.
