What is the ~closet pub~ for ~x~ beer?
Logical Approach:
*find geographically closest item*
*remove* unwanted fields
Pipeline:
db.beer.aggregate( [
{ $geoNear: {
*near: { type: "Point", coordinates: [ -0.1, 52.1 ] },*
distanceField: *"dist.calculated",*
maxDistance: *2000000,*
*query*: { beer_name: "Heineken" },
includeLocs: *"dist.location",*
*num: 1,*
spherical: true
} },
{ '$project' : { '_id' : 0, 'venue_name' : 1, 'venue_city' : 1, 'dist' : 1 } },
] ).pretty()
