easy way to do it is to limit the results number.
working with a limited number of suppliers you can have AI-based search for nearly anything: electronic, travel booking, finnces, etc.
I guess this is how Siri works / is going to work (no Siri access in my country).
Then, all you need is marketing to call it AI :)
