ItemSearch requests require that you specify a search index. This is because searching across the millions of products in Amazon databases would take too long. Product Advertising API does, however, enable you to search across multiple search indices using the All or Blended search indices.

All Search Index

You can use the All search index to do an ItemSearch search through all search indices. There are, however, a number of restrictions placed on this request: the only parameter that you can use in the request is Keywords, and you cannot, for example, sort results.

	Note
	You cannot use the All search index in an ItemLookup request.
