Overview

A multi-bucket aggregation which returns document counts for custom numerical ranges, which define the buckets

Examples:


search do
  aggregation :clicks do
    range field: 'clicks',
          ranges: [
            { to: 10 },
            { from: 10, to: 20 }
          ]
  end
end

Using custom names for the ranges


search do
  aggregation :clicks do
    range do
      field 'clicks'
      key :low, to: 10
      key :mid, from: 10, to: 20
    end
  end
end
