Bagaimana cara mencocokkan elemen agregat ($graphLookup) di MongoDB?

reportingHierarchy adalah array objek reguler di sini sehingga Anda dapat menambahkan $match berikutnya tahap ke agregasi Anda

db.employees.aggregate( [
   {
      $graphLookup: {
         from: "employees",
         startWith: "$reportsTo",
         connectFromField: "reportsTo",
         connectToField: "name",
         as: "reportingHierarchy"
      }
   },
   {
      $match: {
        $and: [{ "reportingHierarchy.name": "Andrew" }, {"reportingHierarchy.name": "Eliot" }]
      }
   }
] )
