The Version parameter specifies the version of the A2S to use.
During testing and for examples, you might wish to use "&Version=2100-01-01" in your A2S queries. This will force A2S to use the latest version of the web services.
But, in your real code, specify the actual date of the latest Version at the time you test your code (see: the A2S Release Notes for information about each version). This will protect you from changes introduced in later versions.
Applies to all operations.
The above ItemSearch operation returns products associated with the Home / Home / Tools & Hardware / Specialty Stores / Contractor Supply browse node (1259929011) and the Tools search index. Only products which match the keywords are returned.
The Request response group returns all of the parameters and their values that were submitted in a request. This helps with debugging, but be aware that all parameters, including unrecognized/invalid parameters, are included.
The Large response group returns a large amount of information about each item in the response.
Sorry. I was unable to perform the query because of limits set by Amazon.com.
