Hi Sohail, In my previous mail, I mentioned about storing categories as separate record. You should store and index Category name, MainProduct name as separate record. Index ChildProduct name, MainProduct as separate record.
When you want the count, 1. Retrieve the main product name matching the category 2. Retrieve the list of child products matching the main product You may need to two query but it is worth. You don't need to delete and bunch of records.
