Is there a way to return exact number of products per page with mercello helper query ?

When i search , for example 10 products on 1st page , i got only one product (other 9 are not available) ?

list = merchelloHelper.Query.Product.TypedProductContentSearch(1, 10, order_by, Merchello.Core.Persistence.Querying.SortDirection.Ascending);

It makes pagination impossilble . Only way is to return all products , then create pagination manualy with list.skip(page*itemsperpage).take(itemsperpage)
