Very nice explanation. Can we do some thing like if tag is empty after elemMatch filters,
don't show the records.

I have been bouncing around for three days now, I know it shoul be easy but it seems is something not practiced by mongodb users and I just dont know why. I needed to get all the array fields at the same level as the parents columns and repeat the value of the parent columns for each sub-record of the array. To be used in an excel for a pivot table just so you know what is the purpose.
