The associated query to multiple tables

// Customer.java
@Entity
public class Customer {
 
    @Id public long id;
    public boolean male; 
    @Backlink
    public ToMany<Order> orders;
 
}
 
// Order.java
@Entity
public class Order {
 
    @Id public long id;
    public boolean isCash;
    public ToOne<Customer> customer;
 
}

If the tables like this, I want use the DataSubscription to observer the data which Customer is male and Order isCash? What should I do ？Thank you very much !

Do objectBox support multiple table queries like SQL?
