[Developers] mql_filter parameter to search API

[Shawn Simister]

Wow, great minds think alike! I was just experimenting with the same 
type of idea last week. You can check out my rough hack here 
<http://answers.narphorium.user.dev.freebaseapps.com/index?q=What%20is%20the%20height%20of%20the%20Empire%20State%20Building?>. 
If you look at the source of the app you'll find also the MQL queries 
that I use to look up the data.
