Question

Lets have theese objects:

public class Obj1
{
    public string Id { get; set; }
}

public class Obj2
{
    public string Id { get; set; }
    public string Obj1Id { get; set; }
}

public class Obj3
{
    public string Id { get; set; }
    public string Obj2Id { get; set; }
}

I use include like this:

var objs3 = session.Query<Obj3>()
    .Customize(x => x.Include<Obj3>(o3 => o3.Obj2Id))
    .Take(1000)
    .ToList();
foreach (var obj3 in objs3)
{
    var obj2 = session.Load<Obj2>(obj3.Obj2Id);
    //do something with it
}

My question is, is there possibility to add to query something like .Where(o2 => o2.Obj1Id == “some/Id”)? Query knows nothing about Obj2 on the client (Linq) side, but server side works with them, because this makes only one request to the DB.

I try to look how to works indexes and projections, but no luck with some constructions. Maybe my view is deformed from relational databases and there are other solutions, that need my structures to be redefined…

My other solution is to add Obj1Id to Obj3, but that will makes duplicites (I can live with this 😉 )

Some extra info to objects:
– Obj1 is unique for each customer, so there is about 200 documents
– Obj2 : Obj3 is 1 : 1 siblings, each with own point of view properties, both about 100.000 for each customer

Bonus question: Is there something like Inclide chaining? Including Obj1 inside of Including Obj2? (this I won’t use, is just question)

Answer 1

No, you can’t add condition to the include.
It is either all the way in, or not at all.
