Subject Re: can't delete from an index using IndexReader.delete()
Date Mon, 23 Jun 2003 04:53:48 GMT
Hi,

Can you check the return value of your reader.delete(...); call? 
According to the Javadocs, it should return the number of documents it 
deleted, maybe you can verify that it is deleting an entry?
