It's risky.
How would you get the IDs to know which ones to delete? A separate
reader running on the side?
The problem is, as IndexWriter merges segments, the IDs shift. Any
reader you have already open won't see this shift (until you reopen
it), so you could end up deleting the wrong IDs.

hello,
what would happen if I modified the class IndexWriter, and made the
delete
by id method public?
I have two fields in my documents and I got to be able to delete by
those
two fields, (by query in other words) and I do not wish to go trunk
version.
I am getting quite desperate, and if not found a solution I will
have to
make my documents with 3 fields, a, b and a + b so I can delete by a
and b.
Best.
could there be a side effect?
Best.
