Ryan McKinley commented on SOLR-264:
------------------------------------
Dooh. I was worried about this at first, but it did not seem to matter.
Perhaps my dataset isn't big enough to get itself stuck in a keep sorting
loop...
Do you see any holes in:
private static class RandomScoreDocComparator implements ScoreDocComparator {
final long start = System.currentTimeMillis();
public int compare (ScoreDoc i, ScoreDoc j) {
int vI = new Random(start+i.doc).nextInt();
int vJ = new Random(start+j.doc).nextInt();
return vI - vJ;
}
public Comparable sortValue (ScoreDoc i) {
return new Integer(new Random(start+i.doc).nextInt());
}
public int sortType() {
return SortField.CUSTOM;
}
};
> Support 'random' sort order
