如何通过 json 中的深场在 mongo 排序中获得 20 个文档？
我在 MongoDB 中的文档：
{
"_id": {
"$oid": "5e90276937b54857689435733"
},
"user_id": "",
"nickname": "",
"platform": ""
"invites": {
"$numberInt": ""
},
"hide_game_stats": false,
"game_data": {
"player_info": {
"level": {
"value": {
"$numberInt": "96"
},
"rank_icon_url": ""
},
"platform": "battle"
},
"warzone": {
"battle_royale": {
"timePlayed": {
"$numberInt": "55789"
},
"score": {
"value": {
"$numberDouble": "202485"
}
},
"kd_ratio": {
"value": {
"$numberDouble": "1.71"
}
},
"kills": {
"value": {
"$numberInt": "217"
}
},
"games_played": {

}
},

}
},
"top_5": {

}
},
"top_10": {

"$numberInt": "15"
}
},
"top_25": {

}
},
"win_rate": {

}
}
},
"plunder": {

},
"cash": {

},
"score": {

您不要在排序中使用 $match 操作：findOptions.SetSort(bson.D{{"game_data.warzone.battle_royale.kills.value", -1}})
