Normally an ID should be indexed as Field.Index.UN_TOKENIZED.

That was the problem - the id was not tokenized. Thanks for your

Hi John,
Are you sure you made the id "tokenized" while indexing? I could
overcome
this issue by having a tokenized field, which was used for the
deletion as
below.
document.add(new Field("id", id, Field.Store.YES,
*Field.Index.TOKENIZED*));
Thanks

I just discovered some strange behaviour with deleted documents.
I do a
search for documents with a certain query and delete one using
IndexWriter.deleteDocuments(Term) using a key for the term. Then I
repeat
the search and the document is still there because I use a custom
HitCollector which does not check IndexReader.isDeleted(int).
That is
all
expected.
Hmm -- once a document is deleted, your HitCollector won't ever
see it.
During searching, isDeleted is called per document at a very low
level.
If your HitCollector is seeing it, it sounds like it wasn't really
deleted.
Are you sure you closed the IndexWriter and then reopened your
searcher,
so
that the searcher will see the deletion?
But when I try to show the deleted document by searching by key
using
the
same term it was deleted with, it is not found. So it seems that
the
term
(id:MYKEY) is removed from the index.
This is odd -- the document should either be deleted (entirely),
or not.
You shouldn't get different behavior if you search for the doc one
way
vs
another.
So I was surprised that the term for the id was removed but not the
other
terms for document.
That make two of us!
Mike
