input: Write a function to create an instance of the "sru" class and perform a search using the "search" method, passing in a query string and optionally a collection name, start record number, maximum number of records to return, and record schema. The function should return a "response" object containing the results of the search. If the search is successful, the function should assert that the response is not False.
