I'm trying to create a runtime field within an index template. I can easily divide the values of two integers like this:
emit(doc['bounce_time'].value / doc['session'].value)
EG
bounce_time: 100 / session: 25 = 4
However I have a hash field that is essentially a uuid. Instead of dividing the bounce_time
by the session
Id like to divide the bounce_time
by the cardinality of the field uuid
: emit(doc['bounce_time'].value / doc['uuid'].value)
.
I'm not entirely sure how to get the cardinality of the uuid
string field before doing the division. Any help?
Thanks
