I think you can do this with search suggestion like algorithms. First, you should categorize the search log, e.g. Thai Restaurant or Chinese Restaurant or KFC should be assigned categories including Restaurant.
When user is typing, figure out from the search log which keyword is nearest to the input and take that keyword's categories as the user input's category.
