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++;
     }
   }
