Ok, thanks. I got stuck on trying to extend TopFieldDocCollector and didn't
notice it's also a TopDocsCollector. A couple of questions about Solr:
1. In Solr's DocSetDelegateCollector, a lot of code is duplicated. Why not
this:
public void collect(int doc) throws IOException {
collector.collect(doc);
super.collect(doc);
}
2. Why does acceptsDocsOutOfOrder return false if it's just collecting IDs?
