多查询firebase

Question

我有以下子数据：

Jeans
 gender: "female"
 imageOfClothes: "url"
 name: "Jeans"
 price: "1999" 
 type: "clothes"

我想在tableView上显示以下参数：性别-女性，类型：衣服。

我的查询如下：

let ref = Database.database().reference().child("Clothes/")
            let query = Ref.queryOrdered(byChild: "gender").queryEqual(toValue: "male")

            query.observe(.value) { (snapshot) in
                var tempClothes = [Clothes]()

                for child in snapshot.children {
                    if let childSnapshot = child as? DataSnapshot,
                        let dict = childSnapshot.value as? [String:Any],
                        let name = dict["name"] as? String,
                        let gender = dict["gender"] as? String,
                        let price = dict["price"] as? Int,
                        let type = dict["type"] as? String,
                        let imageOfClothes = dict["imageOfClothes"] as? String,
                        let url = URL(string: imageOfClothes) {

                        let clothes = Clothes(name: name, price: price, imageOfClothes: url, gender: gender, type: type)
                        tempClothes.append(clothes)
                        print(tempClothes)
                    }
                }

我不知道如何使用多个查询。 这是行不通的：

let query = ref.queryOrdered(byChild: "type").queryEqual(toValue: "clothes").queryOrdered(byChild: "gender").queryEqual(toValue: "female")
