Hey,

With the documents:  
documentA: { "code": ["foo", "bar"] }  
documentB: { "code": ["foo", "foo"] }  
documentC: { "code": ["bar", "quux"] }  
documentD: { "code": ["quux", "bar"] }

I would like to get the following statistics:  
count\_total: 8  
count\_foo: 3  
count\_bar: 3  
percentage\_foo: 37,5%  
percentage\_bar: 37,5%

The use case is that we want to get an alert if a percentage of a specific value is above a certain number. And possibly a dashboard with the percentage over time, using the @timestamp field.
