      Allow for the simple creation of a wildcard index that indexes specific patterns below the wildcard:

       

      db.collection.createIndex(
        { "FieldHolder.$**.SearchSort": 1 }
      )
      

       

       

      To capture only the SearchSort fields in an example like this:

       

       

      {
          FieldHolder: {
              Field1: {
                  Meta: { Some: "Metadata we dont want to index" },
                  More: { Metadata: "we don't want to index"},
                  Value: "Some Value",
                  SearchSort: "some value"
              },
              Field2: {
                  Meta: { Some: "Metadata we dont want to index" },
                  More: { Metadata: "we don't want to index"},
                  Value: 1,
                  SearchSort: "1",
              },
              Field3....
          }
      }
      

       

      This would also more easily allow the implementation of non-sparse indexing on wildcards, where you could forcibly assume the existence of some field (SearchSort in this case)
