Enhancing Restaurant Search Functionality for Improved User Experience

**Problem Description:**
Users often struggle to find specific restaurants on the website due to the limited search functionality according to the selected location. Additionally, users may not always know the exact names of the restaurants they are looking for in that specific location, further complicating the search process.

**Solution:**
I would like to add a functionality to the search restaurant name feature that provides suggestions as the user types. When a user starts typing a single word, the search bar should automatically display all the restaurants in list below that match that word in selected location,even if the user doesn't know the full name. As the user continues typing, the suggestions should refine based on the input, showing restaurants whose names start with or contain the typed letters.

Start by locating the restaurant-name search interface and the code that applies the selected location filter; the issue does not name files, tests, or an entry point. Trace how restaurant results are loaded and displayed, then define completion as location-scoped suggestions appearing while typing and narrowing for both matching prefixes and contained text.
