Does DynamoDB support using one of the set datatypes in a table's primary key?

Question

I'm a huge fan of CouchDB and am completely in love with map functions that emit more than once per document. I am wondering if something marginally similar can be achieved in DynamoDB, by using a string or number set type as part of a hash-and-range primary key, either as the hash or range attribute, so that the same item can be queried in multiple ways.

Thanks!
