You can use the terms aggregation.
{
"size": 0,
"aggs" : {
"langs" : {

roundUp <- function(x) 10^ceiling(log10(x))
This actually also works when x is a vector:
> roundUp(c(0.0023, 3.99, 10, 1003))
[1] 1e-02 1e+01 1e+01 1e+04

How to determine if a number is a prime with regex?
...lly, is there zero or one character-- or, per what I mentioned above, n == 0 || n == 1. If we have the match, then return the negation of that. This corresponds with the fact that zero and one are NOT prime.
