My documents contain a field called SORT_ID, which contains an int that
increases with every document added to the index. I want my results to be
sorted by it.
Which approach will prove the best performance:
1) Zero pad SORT_ID field and sort by it as plain text.
2) Sort using SortField for an INT.
3) Trust that using INDEXORDER will always return the same order as SORT_ID,
and use that.
My experience is that #3 works very well in terms of performance, much
better than sorting on any arbitrary field. I haven't ever noticed a
problem with it not working. Good luck!
