I recently downloaded a trial version of 80-20 Retriever (ver. 3.0). and am quite impressed with it's indexing and search capabilities. Alas, I just learned that the company that developed the software orphaned it last June and now focuses exclusively on the "enterprise" market. The "personal" version of 80-20 Retriever that I downloaded is no longer available. So, what are others using to index and search your hard drive and email contents?
