Well, you're not giving us much to go on here other than code inspection.
It would be much more useful to give us the exception trace, try using
e.printStackTrace();
As an added benefit, that often allows me to figure out the problem
myself, which is faster.....
But at a guess, you're destroying your index with the call
FSDirectory directory = FSDirectory.getDirectory(indexDir,true)
because the second parameter is set to true, causing a new
directory to be created or the old one to be erased. This call
as been deprecated in Lucene 2.1, what version are you using?
And the line
System.out.println("The value of Deleted Document is " +directory);
confuses me a lot since directory is an FSDirectory, not a string.

Hi,
I am trying like this in my code but control is going in catch instead of
try block
else {
//if (LOG.isInfoEnabled())
//LOG.info("Document " + url + " has no
OBJECT links.");
try{
//LOG.info("Document " + url + "
has no OBJECT links.");
surl1=url.toString();
String
indexDir="E:\\eclipse\\310307\\objtest\\crawl-result\\index";
FSDirectory directory =
FSDirectory.getDirectory(indexDir,true);
//LOG.info("Document " + directory + " is
the DIRECTORY VALUES.");
IndexReader reader = IndexReader.open
(directory);
if(true){
System.out.println("The value of Deleted
Document is " +directory);
Term term = new Term("url", surl1);
int deleted = reader.deleteDocuments(term);
}
directory.close();
reader.close();
}
catch(Exception e){System.out.println("Exception
Found In Block");}
//IndexReader ir=new IndexReader(dir);
//setNonObjectUrl(surl1);
//return surl1;
}
return doc;
can you brief me where did I go wrong??
