javascript - 如何从 JavaScript 函数返回文档/节点？

Question

如果我执行类似 select from #12:1 的操作，显然，它将返回完整文档:

{
    "result": [
        {
            "@type": "d",
            "@rid": "#12:1",
            "@version": 1,
            "@class": "Package",
            "name": "MsPortfolioStack4.Repository-1.0.4549.25474-alpha",
            "p_name": "MsPortfolioStack4.Repository",
            "p_ver": "1.0.4549.25474-alpha",
            "tags": [
                "#14:1",
                "#14:2"
            ],
            "@fieldTypes": "tags=z"
        }
    ],
    "notification": "Query executed in 0.022 sec. Returned 1 record(s)"
}

现在，如果我有一个 JS 函数可以执行此操作:

function return_node(query) {
    return query;
}

然后我执行select return_node((select from #12:1))，我只得到RID:

{
    "result": [
        {
            "@type": "d",
            "@rid": "#-2:1",
            "@version": 0,
            "return_node": [
                "#12:1"
            ],
            "@fieldTypes": "return_node=z"
        }
    ],
    "notification": "Query executed in 0.058 sec. Returned 1 record(s)"
}

是否可以返回实际的扩展文档而不仅仅是 RID？目前最快的方法似乎是遍历结果，但这是多余的。

可以更改JS函数

var db=orient.getDatabase();返回 db.query(查询);

并执行select Expand(return_node("从#12:1中选择")) from (select return_node("从#12:1中选择"))
