IndexWriter index = new IndexWriter("index",objAnalyzer, true );
 
What is "index", this is the first parameter you are passing ? 
It is the path where you store you index file on your hard disk so your path has to be something
like C:\index. You have to create the index folder explicitly.
 
You may have to change this line also
Searcher objIndexSearcher = new IndexSearcher("index");

Hi all

I made a mistake when I copied and pasted the code.
The actual code is as follows:

import org.apache.lucene.analysis.Analyzer;
import org.apache.lucene.analysis.standard.StandardAnalyzer;
import org.apache.lucene.document.Document;
import org.apache.lucene.document.Field;
import org.apache.lucene.index.Term;
import org.apache.lucene.index.IndexWriter;
import org.apache.lucene.queryParser.QueryParser;
import org.apache.lucene.search.Hits;
import org.apache.lucene.search.IndexSearcher;
import org.apache.lucene.search.Query;
import org.apache.lucene.search.TermQuery;

import org.apache.lucene.search.Searcher;

public class testLucene
{
private static final String[] strSTOP_WORDS =
{
"and",
"are",
"was",
"will",
"with" };
private void test() throws Exception
{
Analyzer objAnalyzer = new StandardAnalyzer();
IndexWriter index = new IndexWriter("index",objAnalyzer, true );
Searcher objIndexSearcher = new IndexSearcher("index");


Document d = new Document();

d.add( Field.Text("name","Ebrahim Faisal"));
d.add( Field.Text("address","New York"));
d.add( Field.Text("designation","Software Engineer"));
d.add( Field.Text("xyz","123 IndexWriter index"));

index.addDocument( d );

d = new Document();

d.add( Field.Text("name","John Smith"));
d.add( Field.Text("address","India"));
d.add( Field.Text("designation","Sr. Software Engineer"));
d.add( Field.Text("xyz","456 StandardAnalyzer true"));

index.addDocument( d );



index.optimize();
index.close();


Query objQuery = null;

objQuery = QueryParser.parse("John", "name"
, objAnalyzer);


Hits objHits = objIndexSearcher.search(objQuery);


for (int nStart = 0; nStart < objHits.length(); nStart++)
{
d = objHits.doc(nStart);
System.out.println(" address "+d.get("address"));
}

}
public static void main(String[] args) throws Exception
{
new testLucene().test();
}
}
