How might one use the Amazon Product API to get a list of unreleased items?

Question

This one's been giving me a headache for a while now. There is one similar question around here, but it's somewhat ambiguous and appears to be unresolved.

I would like to use Amazon's product API to find items in various categories that have yet to be released, that is, items which have a release date which is greater than today's date. From what I can make of it, there may be a way of getting the release date as a response to a query about an item, but I would prefer to make it a part of the query. It's simply impractical to request all of the items in a category and check their release dates individually.

The goal is to get the ASINs of every item on a page such as this one, which is a list of unreleased children's books about animals. This is just an example, of course.

I'd prefer a PHP solution, but really, anything will do. Please feel free to ask me to clarify any points if need be. Thanks in advance!

You can use the ItemSearch operation on the Product Advertising API with the following parameters:

# Specify the SearchIndex  
SearchIndex = 'Books'

# and the category you want to look at. 
BrowseNode = '2787'

# Use the Power parameter to search for items that will be published
# in the future (here: between January 2013 and June 2013)
Power = 'pubdate:after 01 2013 and pubdate:before 06 2013'
