Hi,
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.
#3 - to sort by order indexed, there is no need to have a custom
incrementing field. I'd recommend dropping SORT_ID unless you need
it for some other purpose.
