Re: search across models
thank you dennis,
what you suggested is a difficult process where we need to look into
performance its the query gets more complex and database gets bigger which
is obvious.
but its a good idea. i will try that for a while.

Re: search across models
thank you joey,
but i want to build search for queries like
1. restaurants in city1
2. city1 restaurants
3. Chinese restaurants
4. Chinese restaurants in city1
5. vegetarian restaurants in city1
6. vegetarian american restaurants
the above are exact search queries we get from template.
i wrote
restas = restaurant.objects.filter(Q(name__contains =
request.REQUEST.get('title')) & ~Q(city__name='') )
this works fine to search with restaurant name.
i really have no idea on how to get results if the search phrase is
complex.
