This is a definitely much better.

There is one small improvement which you could make to do even better.
The search criteria are only matched against the product descriptions. I would also like to match it against the filenames of the products.
In the old purchase history I was able to search for "UD_" to find updates to the products. With the current search you cannot do this.

Even better would be to have a list for all the updated products.

Thanks
