I try to normalize the vote field, for that, I use Group in order to find the Min and Max values of all document
The problem is that I get one a result on the pipeline but I need to subtract the min and max from all the documents
How I bring back all documents with additional Min and Max values as a field on all the documents?
I see that you have completed the lab successfully
However, if you have any questions regarding the aggregation pipeline feel free to reply on the discourse inbox message thread initiated by me.
