REST API - /orders - Filter orders by products purchased in the order

[hperezsald92b7]

Hello, 

I want to figure out how to use the /orders endpoint and use the searchCriteria parameter to only get orders that contain a specified product. 

So far, I am able to successfully get all orders, and use the searchCriteria[pageSize] and searchCriteria[currentPage] for pagination. 

I'm guessing I can use the searchCriteria[filterGroups] parameter, but I'm not sure what field I would use to filter by items purchased. 

Thanks.
