Matching 2 control matches for each case individual in r with matchit{MatchIt}

I'm trying to subset matched data with matchit function from MatchIt package in R. I want to match 2 control matches for each case individual by AGE and SEX variables. I've tried to use method="exact" and method="nearest", but I couldn't find the option to limit the number of control matches. Does anyone have any idea how to solve it within the function?

Hopefully you've solved it, but what you need is method="nearest" (if you want nearest neighbor matching), exact=c("sex", "age"), ratio=2. I strong recommend full matching though, using method=full.
