{  
name:"bach",  
introduction:"bwv1004"  
works:[  
{work\_name:"bach bwv1004"},  
{work\_name:"bach violin concerto"}  
]  
}

I expect to get following answer when searching "bwv"  
{  
introduction:"bwv1004",  
works:[  
{work\_name:"bach bwv1004"}  
]  
}

It looks like `works` is an array, I'm not sure you can just return part of that in a query though.
