Return Total number of items found in the result with limit for pagination.

[Fahim]

How can I return the total number of search items found in the result with limit for pagination.

My query is given below. I am also grouping the food item result by restaurant_id.

OR r IN restaurant_food_search

    SEARCH ANALYZER(r.name IN TOKENS('burger', 'text_en'), 'text_en')

    //SORT r.price.current.price LIMIT 0, 15

    COLLECT restaurant = r.restaurant_id into items

    return {restaurant, items: items[*].r, item_count : LENGTH(items[*].r)}
