I am in the process of building an mobile application (iPhone/Android) and want to store the application data onto Amazon\'s SimpleDB, because we do not want to host our own ser
The upcoming release of Simple Savant (a C# persistence library for SimpleDB which I created) will support both attribute spanning as described by Mocky and full-text searches of SimpleDB data using Lucene.NET.
I realize you are probably not building your app in C#, but since your question is a top result when searching for SimpleDB and full-text indexing it seemed worth mentioning.
UPDATE: The Simple Savant release I mentioned above is now available.
