fix(error-handling): improve search results error handling

Added a try-except block around the search results API call to handle potential errors gracefully. Now, if an exception occurs, an error message is logged, and the user is redirected to an error page with a 500 status code. This improves user experience by providing clear feedback when the search functionality fails.
