Mixing search indexes using the Amazon product advertising API

Question

How to search using two and only two search indexes in the Amazon Advertising Advertising API, such as DVD and Books.

Answer 1

You can not. You can:

• Use a mixed index that will look for everything, or
• Submit two ItemSearchRequests, one for the Books index and one for the DVD index. That's why Amazon allows you to send multiple requests in a single API call (using SOAP versions).
