Possible to fetch a document without all fields (for performance)?

Say I have a query result for the term Linux... now I just want the 
TITLE of these documents not the BODY.

To further this scenario imagine the TITLE is 500 bytes but the  BODY is 
50M.

The current impl of fetching a document will pull in ALL 50,000,500 
bytes not just the 500 that I need.

Obviously if I could just get the TITLE field this would be a HUGE speedup.

Is there a somewhat simple and efficient way to get a document with a 
restricted set of fields?  Digging through the API it didnt' seem 
obvious and using the SegmentReader directly didn't seem fun.

Kevin
