Hi, I had an exsisting index file with the size 20.6 GB...I havent done any optimization in this index yet.Now I had a HDD of 100 GB,but apparently when I create program to optimize(which simply calls writer.optimize() to this indexfile),it gives the error that there is not enough space on the disk. I read that the size needed to optimize the index is twice as the original index size...then it should be around 40 GB instead...I confuse why the size of 100 GB is insufficient to do the optimization... Can anyone help me? THanks and Regards, Maureen
