Re: How do I delete?
OK, the reference field was not parsed. See:
}else if(key.equals(reference) ) {
reference = value;
Field fReference = new Field(reference,value,true,true,false);
doc.add(fReference);
On another examination of my program, the delete does seem to be
working. At least the delete returns a value of 1 saying it deleted one
record. However the search still keeps finding the old record. I am
doing an optimize after each index batch.
Unfortuately the old record is still there even after I delete it. So I
deleted it and replaced it with the date in a different format to see if
it was really replaced. The date field indicates I've still got the old
data in there for some reason. Is data cached somewhere?

First off, are you absolutely certain you are closing the reader? it's
not in the code you listed.
Second, I'd bet $1 that when your documents were indexed, your reference
field was analyzed and parsed into multiple terms. Did you try searching
for the Term you're trying to delete by?
(I hear luke is a pretty handy tool for checking exactly which Terms are
in your index)

:
: reader = IndexReader.open(database);

: System.out.println(Delete exception;+e);

How do I delete?
I've been merrily cooking along, thinking I was replacing documents when
I haven't. My logic is to go through a batch of documents, get a field
called reference which is unique build a term from it and delete it
via the reader.delete() method. Then I close the reader and open a
writer and reprocess the batch indexing all.
Here is the delete and associated code:
reader = IndexReader.open(database);
Term t = new Term(reference,reference);
try {
reader.delete(t);
} catch (Exception e) {
System.out.println(Delete exception;+e);
}
except it isn't working. I tried to do a commt and a doCommit, but
those are both protected. I do a reader.close() after processing the
batch the first time.
What am I missing? I don't get an exception. Reference is definitely a
valid field, 'cause I print out the value at search time and compare to
the doc and they are identical.
Thanks,
Jim.

Re: How do I delete?
I've had success with deletion by running IndexReader.delete(int), then
getting an IndexWriter and optimizing the directory. I don't know if
that's the right way to do it or not.

Re: How do I delete?
Thanks, I'd try that, but I don't think it will make any difference. If
I modify the code to not reindex the documents, no files in the index
directory are touched, hence there is no record of the deletions
anywhere. I checked the count coming back from the delete operation and
it is zero. I even tried to delete another unique term with similar
results.
How does one call the commit method anyway? Isn't it automatically called?
Jim.

Re: How do I delete?
Well, in LuceneRAR, the delete by id code does exactly what I said: gets
the indexreader, deletes the doc id, then it opens a writer and optimizes.
Nothing else.
