Search is a massive load on servers at the best of times.The database has to index all fields to be searched, and builds indexes to those fields to speed up searching. Changing to indexing and searching for 3 letter combinations, instead of 4 or more as it is presently, would add significant overhead and server load, and could even double the load for search.I have products from suppliers such as DNA, so I too am pretty darn anxious to see a 3 character search key. It is coming, I'm told, but it's a few weeks away yet, at least, until the db server architecture will be robust enough to handle the extra load.
