index sorting merge

Hi,

I specified a  SortingMergePolicy in my case. I find only the first N-1
segments are sorted as expected, the last segment is still disordered  when
I call forceMerge(N), N > 1,

I think it is by design, but is there any way to make all segments sorted.

Thanks !

You should upgrade to newer versions of Lucene, where all segments are
sorted, not just merged segments.
