Thanks again, Alex.

>I saw a demo about 2 months ago, but this product was about $15,000 including a high-speed scanner and a computer. Unbelievably it was created in Access and there was a more expensive version that used sql-server as a back-end

This is going to blow the budget!

I found a software called dtSearch at Hallogram, and it seems to be somehow adequate, and affordable, so I asked additional info about it.

Fernando
