Correct. Occasionally one hit's a "major" merge and as few as 1 segment is produced. Think about the odometer in your car (if you have one that spins). Each digit is the number of segments of that size... so the total number of segments in the index is the total of the digits. You naturally get back to a single segment whenever it rolls over to the next highest power of 10 (mergeFactor=10). -Yonik http://www.lucidimagination.com
