有没有一种方法可以查询嵌入式文档？

Question

在MongoDB Shell上，如何查询下面的“商店”文档，以便获得价格低于10的所有书籍的书名？我希望能回来：[“世纪风俗”，“白鲸”。

在我的旧javascript JSON解析器上，我通常会使用： $ .store.book [？（@。price <10）]。title ...但是我正在努力寻找与Mongo类似的东西。谢谢！！！

{
    "store": {
        "book": [
            {
                "category": "reference",

                "title": "Sayings of the Century",
                "price": 8.95
            },
            {
