I am looking for a place to stay . The hotel does n't need to have free parking and should have a star of 4
request((_:search,area,?);(_:search,type,'Hotel'))
system
What area of town would you like ?
inform((_:search,area,'north');(_:search,type,'Hotel'))
user

Great , I have found several guesthouses but unfortunately no hotels   in the north side that are rated 4 stars . Would you be interested in something like that ?
