• expand$: بصورت نرمال، هنگام کوئری گرفتن از یک کالکشن OData، پاسخ سرور موجودیت‌های مرتبط (related entities) را شامل نمی‌شود. با استفاده از expand$ می‌توانیم موجودیت‌های مرتبط را بصورت inline در پاسخ سرور دریافت کنیم.
• select$: از این متد برای انتخاب چند خاصیت بخصوص از پاسخ سرور استفاده می‌شود، بجای آنکه تمام خاصیت‌ها بارگذاری شوند.
• value$: با این متد مقدار خام (raw) فیلد‌ها را بدست می‌آورید، بجای دریافت آنها در فرمت OData.
