RavenDB: how to transform a session.Query into a session.Advanced.DocumentQuery?

Question

I stored the objects of the following classes in a ravendb database:

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; }
}

Thanks to a post (RavenDB: how to retrieve the top nodes in a nested collection?) I have learned how to use session.Query to retrieve from the database all the continents having cities with Name and Address respectively set to "aloma" and "123". I would like to write the same query using session.Advanced.DocumentQuery. So can you please tell me how to transform the following query into a session.Advanced.DocumentQuery: var continents = session.Query() .Where(x=>x.Countries.Any(country => country.Provinces.Any(p=>p.Cities.Any(city => city.Name == "123" && city.Address == "aloma"))).OfType().ToList(); ?

Answer 1

Note, this is probably not the best way to do this but it's the only way I know how. Also, note the following will create an index once executed.

var results = session.Advanced.DocumentQuery<Continent>().Where("Countries,Provinces,Cities,Name: 123 AND Countries,Provinces,Cities,Address: aloma").ToList();

Model structure used:

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

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

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

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