Subject Re: Need help for ordering results by specific order
Date Thu, 19 Jul 2007 02:53:26 GMT

Yes, Mathieu.
I just have the book "Lucene in action" by my hand, it is chinese language
version, it is about lucene1.4, hope it is not too old.
If I use SortComparatorSource, does it means it will be do the sort work at
the user query time?
Can I sort (maybe score it atindexing time)?
