How to perform case-insensitive filtering for inner collections using HotChocolate GraphQL query?

[arjundnair-fingent]

Hi,

I have been trying a lot to find a solution for performing case-insensitive filtering on inner collection properties using HotChocolate GraphQL version 11. I got a method for configuring case-insensitive filtering but it only seems to work for main objects.

The link I referred to configure case-insensitive filtering:
Extending Filtering

This is my class structure:

public class User
{
    public string Name { get; set; }
    
    [UseFiltering]
    public ICollection<Address> Addresses { get; set; }
}

public class Address
{
    public string Street { get; set; }

    public bool IsPrimary { get; set; }
}

public class Query
{
    [UseFiltering]
    public IQueryable<User> GetUsers([Service] IUserRepository repository)
        => repository.GetUsers();
}

Case-insensitive filter works fine with the User class but doesn't work when I try filtering on the Addresses collection inside the User class like this:

query {
  users {
    name
    addresses(where: { street: { contains: "baker" } }) {
      street
      isPrimary
    }
  }
}

But works fine when query is like this:

query {
  users {
    name
    addresses(where: { street: { contains: "Baker" } }) {
      street
      isPrimary
    }
  }
}

How can I implement case-insensitive filtering for the inner nodes too? I used the exact same steps mentioned in the docs in the above given link, and it is from the official ChilliCream team. Please help me.
