docs: Bill Search
  This method returns just a subset of the bill fields by default.
  NOTE: *** This method never uses the cache. Use with caution. ***
  
  Filter Parameters
  
  The following parameters filter the returned set of bills, at least one must be provided.
  Use null for any parameter that is not used.
  
  @param state - Only return bills from a given state (e.g. 'nc')
  @param updated_since - Only bills updated since a provided date (provided in YYYY-MM-DD format)
  
  The API will not return exceedingly large responses, so it may be
  necessary to use page and per_page to control the number of results returned:
  @param page - Page of results, each of size per_page (defaults to 1)
  @param per_page - Number of results per page, is unlimited unless page is set, in which case it defaults to 50.
  
  @return {@link Bills}
