[Developers] Limiting prefix searches

[John Giannandrea]

There are several ways to do this, some better documented than others.

The simplest is with MQL:

[{"artist
":"Nirvana
","name":null,"name~=":"^Never*","release_date":null,"type":"/music/ 
album"}]

You can also use the "surrounds" feature of search to find things that  
have a link to something else with a specific name.

http://www.freebase.com/api/service/search?callback=done&type=/music/album&prefix=nevermi&surrounds=Nirvana

There is a new version of search coming soon which implements custom  
MQL output and post filtering but its not available yet.
