Re: can't delete from an index using IndexReader.delete()

[Jeff Linwood]

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?

Hi,

I am using the latest binary distro (lucene-20030620.jar).  I am
trying to
delete an entry from an index and then add it back with updated
information.
The entry is a content XML piece with some metadata added to the
Document. I
try to delete the entry by using a Term derived by the Field 'id' and
the
value of that field. The value is correct. What happens is that two
entries
exist after executing the code below. 

So, creating a Query for field 'id' with an example value 'abc' will
return
two hits. Any ideas what I am doing wrong? Is this a bug?
Also, if you see anything I am doing stupidly or that can be
improved,
please let me know.
Thanks,
