Missing fields from search?

Just playing around with the API a little to procrastinate..

I'm not sure if I'm doing something wrong, but if I execute something like

/search/?query=Fallout%203&resources=game&field_list=name,id,platform

I only get the name and id returned in the results, no platform data.

Doing a direct query on the object using

/game/20405/?field_list=name,id,platform

seems to work...

The games list resource doesn't return a 'platform' field (so it won't appear in /search or /games) - it's only available on the game detail resource (/game).

Ah, thanks!

Does this mean that one would need to enumerate all of the records returned from a games/ search and then sub-query each game?  For instance, I want to find all XBOX games that are co-op.  Since concept is part of game/ how would get this result set?

Any word on this?  Wouldn't it be very helpful to add platform as a query argument of some sort?  I'm working an emulator plugin for Plex and I use search to get the game ID for a given game name.  If I could pass platform as an argument, I could get the correct game id.  
 
This is especially relevant for games released on several platforms (Madden, NBA Live, etc etc). 
 
Anybody have a good way to do this (besides iterating on all the results' game details)?
