RavenDB：如何在孙子上写查询？

Question

鉴于以下C＃代码，我正在尝试检索所有拥有城市包括的省份的大陆：

1. 一个名称和地址分别设置为＆＃34; Aloma＆＃34;和＆＃34; 123＆＃34;和
2. 另一个名称和地址分别设置为＆＃34; Hemane＆＃34;和＆＃34; 435＆＃34;。

public class Continent
{
    public string Name { get; set; }
    public List<Country> Countries{ get; set; }
}

public class Countries
{
    public string Name { get; set; }
    public List<Province> Provinces{ get; set; }
}

public class Province
{
    public string Name { get; set; }
    public List<Province> Cities { get; set; }
}

public class City
{
    public string Name { get; set; }
    public string Address   { get; set; }
}

我曾尝试使用下面的查询，但它似乎不起作用。你能帮我吗？

Expression<Func<Province, bool>> matchCities = rec =>
      (rec.Cities.Count(fi => fi.Name == "Aloma" && fi.Address== "123") > 0)
        && (rec.Cities.Count(fj => fj.Name == "Hemane" && fj.Address== "435") > 0);

Func<Province, bool> funcMatchCities= matchCities.Compile();

var results3 = session.Query<Continent>()
                      .Where(top => top.Countries.Any(ta => ta.Province.Any(
                                  rec => funcMatchCities(rec))))
                      .OfType<Continent>()
                      .ToList();
