My Lucene queries only ever return one hit

I'm getting started with Lucene.Net (stuck on version 2.3.1). I add
sample documents with this:

    Dim indexWriter = New IndexWriter(indexDir, New
Standard.StandardAnalyzer(), True)
    Dim doc = Document()
    doc.Add(New Field("Title", "foo", Field.Store.YES,
Field.Index.TOKENIZED, Field.TermVector.NO))
    doc.Add(New Field("Date", DateTime.UtcNow.ToString,
Field.Store.YES, Field.Index.TOKENIZED, Field.TermVector.NO))
    indexWriter.AddDocument(doc)
    indexWriter.Close()

I search for documents matching "foo" with this:

    Dim searcher = New IndexSearcher(indexDir)
    Dim parser = New QueryParser("Title", New StandardAnalyzer())
    Dim Query = parser.Parse("foo")
    Dim hits = searcher.Search(Query)
    Console.WriteLine("Number of hits = " + hits.Length.ToString)

No matter how many times I run this, I only ever get one result. Any ideas?

Thanks.  I was hoping it was something simple like this.

Last Boolean parameter can be something like "Not
System.IO.Directory.Exists(indexDir)"
