[Xapian-discuss] creating index for document values

[mark]

i found this in the docs page of sorting, and it says "arrange for
documents to be indexed in date order"? now how do i do this?
thanks again!

"http://xapian.org/docs/sorting.html
If you want to offer a "sort by date" feature, and can arrange for
documents to be indexed in date order (or a close-enough
approximation), "
