This is most likely caused by some misuse of the IndexReader.
How are you using it? Like http://docs.jboss.org/hibernate/stable/search/reference/en/html/ch08s03.html ?
Which ReaderProvider are you using (configuration option "hibernate.search.reader.strategy")? the choice of the ReaderProvider affects the way Search manages the lifecycle of the IndexReaders.
Could you show a stacktrace?

Sorry this questions are not relevant, somehow my mobile browser had decided to hide the stacktrace.

Hi ..
Thanx for your reply.i used FSdierectory provider...

Are you using Lucene 2.4.1 ?
Since 2.4.0 some problems about this were solved:
http://issues.apache.org/jira/browse/LUCENE-1453
http://issues.apache.org/jira/browse/LUCENE-1430

You are probably experiencing some IOException which gets hidden by Lucene (readonly file, wrong permissions, indexcorrupted..).
Try upgrading Lucene.

yes i am using lucene 2.4.1

try setting ,
this will avoid the "DirectoryIndexReader.reopen" and possibly uncover another exception., maybe you found another bug not yet solved from the same family.

i tried it ....i am getting the same exception....

this is my search code
public List search1(String name1,String scat,String cat,int pageNumber)

{

//indexWithHibernate();

//createSomeArticles();
Session session = HibernateUtil.currentSession();
System.out.println("i am in method"+session);
fSession = Search.getFullTextSession(session);
System.out.println("Session test"+fSession);
fSession.beginTransaction();

// create a parser to parse a full text query
QueryParser parser = new QueryParser("name", new StandardAnalyzer());
int id=Integer.parseInt(cat);
System.out.println("parser"+parser);

try {
lucenceQuery = parser.parse(scat+":"+name1+"*"+" OR catpojo.id :"+id);
System.out.println(lucenceQuery);
} catch (ParseException e) {
throw new RuntimeException("Cannot search with query string",e);
}




System.out.println(lucenceQuery+ " "+fSession);
FullTextQuery fp=fSession.createFullTextQuery(lucenceQuery,MovieMasterPojo.class);System.out.println(" size1"+fp.getResultSize());
/////////here only i am getting problem...
fp.setFirstResult(pageSize * (pageNumber - 1)) ;
fp.setMaxResults(pageSize) ;

this.setTotal(fp.getResultSize());
List<MovieMasterPojo> articles = fp.list();
fSession.getTransaction().commit();
System.out.println(" size2"+articles.size());
return articles;
}

Deletes the document numbered doc_num. Once a document is deleted it will not appear in TermDocEnum or TermPostitions enumerations. Attempts to read its field with the @link documentend method will result in an error. The presence of this document may still be reflected in the @link docFreqendstatistic, though this will be corrected eventually as the index is further modified.
