Code
===========
indexFileLocation = @"C:\Index";
Lucene.Net.Store.Directory dir =
FSDirectory.GetDirectory(indexFileLocation, true);

//create an analyzer to process the text
Lucene.Net.Analysis.Analyzer analyzer = new
Lucene.Net.Analysis.Standard.StandardAnalyzer();

IndexWriter indexWriter = new IndexWriter(indexFileLocation, new
StandardAnalyzer(), true);

TextReader txtReader = new StreamReader(@"C:\NewsMetaData.xml");

//create a document, add in a single field
Document doc = new Document();
Field fldContent = new Field("contents", txtReader, Field.TermVector.YES);

doc.Add(fldContent);

//write the document to the index
indexWriter.AddDocument(doc);

//optimize and close the writer
indexWriter.Optimize();
indexWriter.Close();
