Question

I am doing a POC on Search using Lucene.NET.

I fire a stored procedure which fetches around 50000 records from the database.
Thses records I put in the Lucene Index.

Now when the records in database changes, how to update the Lucene index.
Deleting the entire previous indexed and creating a new one will take a lot of time.

I want to append the new records from the database to the existing index.

How can I achieve this.
Any ideas ???

Thanks,
Aneesh

Just use lucene AddDocument method, something like this :

IndexWriter iw = new IndexWriter(folder, GetAnalyzer(), false);
  try
  {
    Document luceneDoc = new Document();
    /// add fields to the lucene document
    iw.AddDocument(luceneDoc);
  }
  finally
  {
    iw.Close();
  }
