Thanks Mike. So can I say that calling optimzie() is really optional? Because I was worrying that these deleted documents would never get cleaned if I don't run optimize() and eventually it would run out of the disk space. What I am trying to figure out here is if optimization is mandatory. I know that optimization would improve the search performance, however it would take a long time to run and the application I am writing needs to update the index very frequently. According to "Lucene in Action", running optimization is not recommended in my case. So would you please advise?
