tags search with amazon cloudsearch

I have products that are tagged with keywords. Tags are not unique to any products.

product 1 - tag1, tag2, tag3

product 2 - tag2, tag3

product 3 - tag1, tag2, tag4

I intend to use Amazon Cloudsearch for a start. What is the optimal way to populate the dataset, as well as to perform the tags search? The query may have multiple tags to search.
