我只需要按
game_data.warzone.battle_royale.kills.value排序的20个文档请告诉我，我该怎么做
我的尝试:
findOptions := options.Find()
findOptions.SetSort(
bson.D{
primitive.E{
Key: "game_data",
Value: bson.D{
primitive.E{
Key: "warzone",
Value: bson.D{
primitive.E{
Key: "battle_royale",
Value: bson.D{
primitive.E{
Key: "kills",
Value: bson.D{
primitive.E{
Key: "value",
Value: -1,
},
},
},
},
},
},
},
},
},
},
) // set the sort function (attempt №1)
findOptions.SetSort(
bson.M{
"$match": bson.M{
"game_data.warzone.battle_royale.kills.value": -1,
},
},
) // set the sort function (attempt №2)
findOptions.SetLimit(20) // set limit to 20 docs
cursor, err := mongodb.CodHubCollection.Find(context.Background(), bson.D{}, findOptions)
if err != nil {
return err
}
最佳答案
您不会在排序中使用$ match操作:
findOptions.SetSort(bson.D{{"game_data.warzone.battle_royale.kills.value", -1}})
