C++ mongodb c++；查询日期范围

c++ mongodb

C++ mongodb c++；查询日期范围,c++,mongodb,isodate,C++,Mongodb,Isodate,我有一个这样的结构： { "_id" : ObjectId("562dcec2430a5684fedce1b0"), "date" : ISODate("2015-10-26T06:57:06.619Z"), "query" : "google com" } auto_ptr<DBClientCursor> cursor = mongo_conn->query("database1.collection1",

我有一个这样的结构：

{
    "_id" : ObjectId("562dcec2430a5684fedce1b0"),
    "date" : ISODate("2015-10-26T06:57:06.619Z"),
    "query" : "google com"
}

auto_ptr<DBClientCursor> cursor =
  mongo_conn->query("database1.collection1",
                    BSON("date" <<
                      BSON("$gte" << BSON(datenow - "1 day")
                      << "$lt" << BSON(datenow))));
我如何过滤那些日期为2015-10-25的查询？ 或者，如果我想过滤一天前询问的查询，是否存在这样的C++表达式：

{
    "_id" : ObjectId("562dcec2430a5684fedce1b0"),
    "date" : ISODate("2015-10-26T06:57:06.619Z"),
    "query" : "google com"
}

auto_ptr<DBClientCursor> cursor =
  mongo_conn->query("database1.collection1",
                    BSON("date" <<
                      BSON("$gte" << BSON(datenow - "1 day")
                      << "$lt" << BSON(datenow))));

auto_ptr光标=
mongo_conn->query（“database1.collection1”，
BSON（“日期”
mongo:：BSONObj日期范围=
BSON（“日期”
