The index I've created
db.gift_ideas.ensureIndex({"sales_rank":1, "rated_by":1, "random":1});

The query, in it's fast form, but that does not return gift_ideas as ordered by the random field
db.gift_ideas.find({"sales_rank":{$lt:1200}, "rated_by":{$nin:["100001450582916"]}, "random":{$gt:0.6071995101094684}}).limit(40)

The query, in it's dog-slow form, where I enforce the sorting
db.gift_ideas.find({"sales_rank":{$lt:1200}, "rated_by":{$nin:["100001450582916"]}, "random":{$gt:0.6071995101094684}}).limit(40).sort({"random":1})

	# I want to put the user in at a random point in the database to start rating products, 
	# to ensure that all products will have roughly the same number of ratings.  Understanding the 
	# formula below isn't critical to understanding my problem.
