    "tech" : [
        {
            "tech_name" : "Magento",
            "user" : "Rahul",
        },
        {
            "tech_name" : "Volusion",
            "user" : "Tina",
        }
    ]
}

我只想将新属性“ verified：true”添加到“ tech_name”：“ Volusion”的“ tech”数组中，这样就可以得到结果，

{
    "_id" : ObjectId("559f85351554febf038b5c70"),
    "company_name" : "Honey Crunch Popcorn Co",
    "tech" : [
        {
            "tech_name" : "Magento",
              "user" : "Rahul"
        },
        {
            "tech_name" : "Volusion",
            "user" : "Tina",
            "verified" : "true"
        }
    ]
}

请帮忙。
