mongodb - 获取 MongoDB 文档 WHERE 状态和日期之间

Question

我需要从订单中获取所有文件 在哪里 :

status == 'paid' AND status == 'delivered' AND
closed_at BETWEEN startDate AND endDate ;

我已经使用以下代码访问了我的 mongoDB 连接:

package main

import (
    "context"
    "fmt"
    "go.mongodb.org/mongo-driver/mongo"
    "go.mongodb.org/mongo-driver/mongo/options"
    "go.mongodb.org/mongo-driver/mongo/readpref"
    "time"
)

func main() {
    mx, err := time.LoadLocation("America/Mexico_City")
    endDate := time.Now().In(mx)
    startDate := endDate.AddDate(0, 0, -1)

    if err != nil { fmt.Println(err); return }

    client, err := mongo.NewClient(options.Client().ApplyURI("mongodb+srv://<userName>:<pass>@someDomain/orders"))
    if err != nil { fmt.Println(err); return }

    ctx, _ := context.WithTimeout(context.Background(), 10*time.Second)
    err = client.Connect(ctx)
    if err != nil { fmt.Println(err); return }
    defer client.Disconnect(ctx)

    err = client.Ping(ctx, readpref.Primary())
    if err != nil { fmt.Println(err); return }

    orders := client.Database("orders").Collection("orders") //here I want to filter with the status 'paid' and 'delivered' and closerd_at between dates.
}

func Bod(t time.Time) time.Time {
    year, month, day := t.Date()
    return time.Date(year, month, day, 0, 0, 0, 0, t.Location())
}

我对文档还有一件事表示怀疑， closed_at有一个格式日期，如:

2020-04-23T21:28:46.642+00:00

还有我的 from和 to日期的格式如下:

startDate: 2020-08-06 00:00:00 -0500 CDT
endDate:   2020-08-07 00:00:00 -0500 CDT

这是我的解决方案:

query := bson.M{
    "status": bson.M{"$in":[]string{"paid","delivered"}}, //only status paid and delivered
    "closed_at": bson.M{"$gt": from, "$lt": to}, //between dates
}

cursor, err := client.Database("orders").Collection("orders").Find(ctx,query)
