Ask HN: Review my prototype for IndexTank search contest

http://attachio.com was my entry to the IndexTank contest. I don't think they were able to review it since i see no activity in my logs from their side. So what is it? Basically, it is a full-text search engine for your files' contents where you submit the files via email (as attachments). It is nowhere near a finished product (i built it as a throw-away prototype). You send an email with an attachment to search@attachio.com and it mails you back when your files are ready to be searched. I just want to explore the idea more, so any input you can provide is greatly appreciated. (I will probably turn it off later and it is pretty fragile with input, so don't rely on it)
