Noob question, I think I'm fundamentally failing to grok something here.
Trying to write a small document management tool, but the indexing isn't
playing ball. I'm reading the Manning Lucene book, and I'm not sure if
something's being lost in translation. In the app, the class that represents
a document has 3 properties that we're interesting in, all strings:
Content (full text content)
DocumentID (Unique ID string)
Folder (the ID of the folder it sits in)
But I can't get it to work. Here's an example app showing my problem:
static void Main(string[] args)
{
DoStuff();
}
private static void DoStuff()
{
Random r = new Random();
if (!Directory.Exists("C:\\MyLuceneTest"))
{
Console.WriteLine("Creating Lucene index directory.");
}
FileInfo indexFolder = new FileInfo("C:\\MyLuceneTest");
IndexWriter writer = new IndexWriter(indexFolder, new
StandardAnalyzer(), true);
writer.SetUseCompoundFile(true);
Document doc = new Document();
doc.Add(new Field("content", r.Next().ToString(), Field.Store.NO,
Field.Index.TOKENIZED));
doc.Add(new Field("documentID", r.Next().ToString() ,
Lucene.Net.Documents.Field.Store.YES, Field.Index.NO));
doc.Add(new Field("folder", "Inbox",
Lucene.Net.Documents.Field.Store.YES, Field.Index.TOKENIZED));
Document doc2 = new Document();
doc2.Add(new Field("content", r.Next().ToString(),
Field.Store.YES, Field.Index.TOKENIZED));
doc2.Add(new Field("documentID", r.Next().ToString(),
Lucene.Net.Documents.Field.Store.YES, Field.Index.NO));
doc2.Add(new Field("folder", "Inbox",
Lucene.Net.Documents.Field.Store.YES, Field.Index.TOKENIZED));
writer.AddDocument(doc);
writer.AddDocument(doc2);
writer.Optimize();
writer.Close();
Console.WriteLine("Added document to index...let's try and find
it.");
IndexSearcher searcher = new IndexSearcher("C:\\MyLuceneTest");
Term t = new Term("folder", "Inbox");
Console.WriteLine("Searching for a document with the 'folder'
field set to 'Inbox'");
Query query = new TermQuery(t);
Hits hits = searcher.Search(query);
searcher.Close();
Console.WriteLine("Number of hits: " +
hits.Length().ToString());
}
This produces zero hits.
If I change the folder field to UNTOKENIZED, I get 2 hits. But if I run the
app again, I still get 2 hits. Shouldn't I be getting 4, then 6?
Fundamentally missing part of the puzzle.
