Can you group beers of a similar IBU together?
Pipeline:
db.beer.aggregate( [
{ '$match' : { 'beer_ibu' : { '$gte' : 0 } } },
{ '$bucketAuto' : {
groupBy: '$beer_ibu',
buckets: 10,
granularity: *'1-2-5'*
} },
] ).pretty()
Result:
{ "_id" : { "min" : *1*, "max" : *2*0 }, "count" : 184 }
{ "_id" : { "min" : *2*0, "max" : *5*0 }, "count" : 535 }
{ "_id" : { "min" : *5*0, "max" : *1*00 }, "count" : 215 }
{ "_id" : { "min" : *1*00, "max" : *5*00 }, "count" : 27 }
