Hi,

There is no constructor for Sort(SortField, boolean) in Lucene API. Which version are you using?

Thanks, Oren Shir

If I understand correctly, when sorting by Sort.INDEXORDER the oldest documents that were added to the index will be returned first. I want the reverse, because I'm more interested in newer documents.

Looking at the source, I see that Sort.INDEXORDER is simply an instance of Sort:

public static final Sort INDEXORDER = new Sort(SortField.FIELD_DOC);

Haven't tried this myself, but you could create your own instance that uses a reverse sort:

Sort reverseIndexOrder = new Sort(SortField.FIELD_DOC, true);

And use that wherever you were using Sort.INDEXORDER.
