If Statement in Painless Script for Kibana's Bucket Script

[lamp123432 (Salt Lamp)]

Is there a good tutorial for using Painless Script in the Kibana's TSVB Bucket Script aggregation?

I'm trying to do a "if" condition, as follow:

If the value is less than 0, add 2^32.

How to do that?

What does this mean? Where can I find a doc online to figure this out?
