Are the adds reflected directly to the index?
Yes. An InstantiatedIndexReader is always current.
You will probably still have to reconstruct your searcher.
I never really looked in to what happends if you don't.
The second statement was wrong. There is no need to reconstruct the
searcher, new documents are immediatly available as search results
after a commit:
public class TestSearch extends TestCase {
public void test() throws Exception {
InstantiatedIndex index = new InstantiatedIndex();
InstantiatedIndexReader reader = new
InstantiatedIndexReader(index);
IndexSearcher searcher = new IndexSearcher(reader);
InstantiatedIndexWriter writer = new
InstantiatedIndexWriter(index);
Document doc;
Collector collector;
doc = new Document();
doc.add(new Field("f", "a", Field.Store.NO,
Field.Index.NOT_ANALYZED));
writer.addDocument(doc);
writer.commit();
collector = new Collector();
searcher.search(new TermQuery(new Term("f", "a")), collector);
assertEquals(1, collector.hits);
doc = new Document();
doc.add(new Field("f", "a", Field.Store.NO,
Field.Index.NOT_ANALYZED));
writer.addDocument(doc);
writer.commit();
collector = new Collector();
searcher.search(new TermQuery(new Term("f", "a")), collector);
assertEquals(2, collector.hits);
}
public static class Collector extends HitCollector {
private int hits = 0;
public void collect(int doc, float score) {
hits++;
}
}
