OK, interesting. This case looks like it'd be a good fit for
iteration-API to access deleted docs. (And, a good case for column-
stride fields, too!).
Thanks for sharing Ian,

Hi Mike
I've got some applications that use lucene purely as a place to store
data, with no searching other than by product id, and have programs
that get all the data out of the store by code like
for (int i = 0; i < max; i++) {
if (!reader.isDeleted(i)) {
Document doc = reader.document(i);
...
}
The index has regular updates and occasional optimizes so normally
does contain deleted docs.
If the isDeleted() method was removed it would only be a minor
inconvenience - I'd be happy to code to any new API calls, or change
the method to call optimize first, or whatever.

We are considering replacing the current random-access
IndexReader.isDeleted(int docID) method with an iterator & skipTo
(DocIdSet) access that would let you iterate through the deleted
docIDs, instead.
At the same time we would move to a new API to replace
IndexReader.document(int docID) that would no longer check whether
the
document is deleted.
This is being discussed now under several Jira issues and on
java-dev.
Would this be a problem for any Lucene applications out there?
How is isDeleted used today (outside of Lucene)? Normally an
IndexSearcher would never return a deleted document, and so "in
theory" a deleted docID should never "escape" Lucene's APIs.
So I'm curious what applications in fact rely on isDeleted, and how
that method is being used...
Thanks,
Mike
