Hello Cristina ,
This is not possible using stat facet. It expect the field to be a number
and it calculates max/min etc based on its different values.
A way to do this would be to add a new field while indexing which would be
the length of the title.
Then performing stats over it might work.
There might be other solutions based on scripting , but i need to explore
...
Thanks
Vineeth
