Dan, when we first purchased Discovery, it was called DrawingSearcher back then. The demo has exactly the same functionality as the registered version and when I called to Docupoint salesman actually asked me "Are you sure you want to buy the software? The functionality is the same."
I couldn't believe my ears! I'm not sure if that salesman is still with the company but if I were his boss and found out about that comment, he'd be gone. We did purchase it though.
When you set it up, you'll probably have it up and running in about an hour or so. It takes a little while to figure out, but it's fairly straight forward.
It creates a dwf of each dwg you index, but then your searches are much more powerful. Discovery searches each and every string of text within the drawing. I love it! It sure beats having to rely on the title fields in our drawing database (AMW) or requiring a drawing number! Let me know if you have any problems with it.
