It seems that group is not supported in nested FOREACH statements. I have the following schema:
data2: {group: chararray,data1: {(lt: chararray,ln: chararray)}}
on which I want to flatten data1, group all pairs of (lt, ln), count, order
DESC, and finally limit 1.
The idea is to extract the most probable pair of (lt, ln) for each group.
How would you recommend me to do that?
