Hi Jamie,
You could try and debug using
IndexReader.numDeletedDocs() ;
On the index to check if the documents are expunged or not.

Subject: Index Growing on Delete
Sent: Jan 22, 2010 14:04
Hi
In our application,on a periodic basis, documents get deleted from the
index. Although the deleted documents correctly cannot be found when
searching the index, our users are complaining that their hard drive is
fulling up, since the index continues to grow in size despite the fact
that the entries should be deleted from the index. I cannot understand
why this is the case since I call both writer.expungeDeletes and
writer.commit(). Any ideas?
Here is my delete function:
public void deleteDocs(Term[] terms) throws MessageSearchException {
logger.debug("delete docs");
try {
indexLock.lock();
openIndex();
try {
writer.deleteDocuments(terms);
} catch (Exception e) {
throw new MessageSearchException("failed to
delete doc from index."+e.getMessage(),e,logger);
} finally {
try {
writer.expungeDeletes(false);
writer.commit();
} catch (Exception io) {
throw new MessageSearchException("failed to
expunge docs from index"+io.getMessage(),io,logger);
}
}
} catch (Throwable t) {
logger.error("failed to delete docs from
index."+t.getMessage(),t);
} finally {
indexLock.unlock();
}
}
As an aside note, we are moving to Lucene 3.0 from 2.9. What is the
equivalent of:
QueryParser queryParser = new QueryParser("body",analyzer);
and "Field.Index.TOKENIZED". If I change this, will my index maintain
compatibility?
Thanks
Jamie
