About the Pi Search Engine: The search engine was written as a VB6 class (DLL) that scans a text file containing 2 billion decimal digits of Pi. The application server runs on a Core2 microarchitecture CPU and the search file itself is stored on a Solid State Drive (SSD), taking less than 25 seconds to scan the entire file.

Download the VB6 source code for the Pi Search Engine. Send me comments or suggestions or any ideas on implementing a faster search method, such as BCD compression!
