If you want to keep every single hit, which is very dangerous for a
large index, you should make a new collector.
Here's an example (pulled from upcoming LIA revision):
public class AllDocCollector extends HitCollector {
List<ScoreDoc> docs = new ArrayList<ScoreDoc>();
public void collect(int doc, float score) {
if (score > 0.0f) {
docs.add(new ScoreDoc(doc, score));
}
}
public void reset() {
docs.clear();
}
public List<ScoreDoc> getHits() {
return docs;
}
}
If you need the results sorted then you should do the sort at the end.

Thanks guys.
Just looking at the examples and I wonder if there is a means to
directly
get the total number of hits. Or is it always necessary to search
for a few
top docs, get the the total number of hits and then create a new
collector
to get all the results?
TopDocCollector collector = new TopDocCollector(5);
searcher.search(query, collector);
int numTotalHits = collector.getTotalHits();
collector = new TopDocCollector(numTotalHits);
searcher.search(query, collector);
ScoreDoc[] hits = collector.topDocs().scoreDocs;
If the later is true, is the code above the best way to do this?
Cheers,
David

The demo code included with Lucene releases was updated in Lucene
2.4 so
that it does not use the Hits class.
