[Developers] different search results from freebase & api

[Tim Kientzle]

You might also try using the "search API", which uses a ranking engine  
to generate "likely" matches for a piece of text.  It's documented here:

http://www.freebase.com/view/guid/9202a8c04000641f8000000006ad84c9

This is very different from mqlread:  mqlread is best when your  
constraints have structure (e.g., you're looking for actors who were  
born in a certain place) and when you want to get all possible  
matches.   In contrast, search is best when you're dealing with  
informal text entry (Freebase.com uses the search API for autocomplete  
and basic search functionality) and you only want the "best" matches.
