What is the difference between stemming and synonyms in Amazon CloudSearch? -

-

i'm looking @ how can tailor cloudsearch analysis scheme provide more relevant search results. (i think) understand conceptual difference between stem , synonym. stems either derivatives, "walk, walking, walked", or depluralisations "company, companies", might want treat same term search point of view. synonyms of course words have same meaning (or meaning that's close enough users might mix , match terms), perhaps "company, enterprise, business", or "email, message".

please correct me on above if i'm wrong.

i'm more wondering, functional point of view, when index built , search performed, how stem treated differently synonym? have derivatives "walk, walking, walked" in synonyms list , have no difference in functionality?
