吗啡过滤错误

Question

我正在使用以下代码过滤评分高于 80 但低于 100 的餐厅

List<Restaurant_M> r = ds.find(Restaurant_M.class)
                             .field("grades.score").lessThan(100)
                             .field("grades.score").greaterThan(80)
                             .asList();

它正在运行，但我得到了 1 个额外的文档，如下所示

{
    "_id" : ObjectId("572eb5df1d739cc73c21fab1"),
    "address" : {
            "building" : "65",
            "coord" : [
                    -73.9782725,
                    40.7624022
            ],
            "street" : "West   54 Street",
            "zipcode" : "10019"
    },
    "borough" : "Manhattan",
    "cuisine" : "American ",
    "grades" : [
            {
                    "date" : ISODate("2014-08-22T00:00:00Z"),
                    "grade" : "A",
                    "score" : 11
            },
            {
                    "date" : ISODate("2014-03-28T00:00:00Z"),
                    "grade" : "C",
                    "score" : 131
            },
            {
                    "date" : ISODate("2013-09-25T00:00:00Z"),
                    "grade" : "A",
                    "score" : 11
            },
            {
                    "date" : ISODate("2013-04-08T00:00:00Z"),
                    "grade" : "B",
                    "score" : 25
            },
            {
                    "date" : ISODate("2012-10-15T00:00:00Z"),
                    "grade" : "A",
                    "score" : 11
            },
            {
                    "date" : ISODate("2011-10-19T00:00:00Z"),
                    "grade" : "A",
                    "score" : 13
            }
    ],
    "name" : "Murals On 54/Randolphs'S",
    "restaurant_id" : "40372466"
}

这没有在 80-100 范围内的分数。这打败了我。谁能告诉我为什么要退回这份文件？

编辑：所以我试着用 JAVA 驱动程序来做这件事，令人惊讶的是我得到了完全相同的结果。代码如下

FindIterable<Document> r = collection.find(
            Filters.and(Filters.gt("grades.score", 80),     Filters.lt("grades.score", 100))
    );

Answer 1

显然，在过去一周我做了所有的头部撞击之后，我无法用吗啡做这件事，所以我求助于 java 驱动程序，下面给出了正确的结果

Bson f1 = Filters.gt("score", 80);
Bson f2 = Filters.lt("score", 100);
Bson f3 = and (f1, f2);

MongoCursor<Document> c = collection.find(
            elemMatch("grades", f3))
                                    .iterator();
