I don't find the way to get percentage in each bucket of an aggregation.
How does Elastic handle percentage calculation ?

Percentage of what?
Depending on what you need, a [bucket script pipeline agg](https://www.elastic.co/guide/en/elasticsearch/reference/2.4/search-aggregations-pipeline-bucket-script-aggregation.html) may work, although it has limitations.
If you just want to convert a raw double (`0.01`) to a percentage (`1%`), I'm afraid this isn't currently possible... you'll have to do the conversion in your application.
