is it possible to unmark_deleted?

Hi @liding1990, Yes, via C++ interface. Would people use if it were be in python?

Thanks for the info, I think it would be logical to have the unmark_delete function in python🙌🏼

@patelprateek this https://github.com/nmslib/hnswlib/pull/334 should add unmark_deleted function in python

I just found out that in version 0.5.2, the unmark deleted feature was exist. When use add_item function with an pre-existing mark_deleted label, add_item will work as "update_item" and "unmark_deleted" the label.

Perhaps the "add_item" name is misleading, but documentation on update function definitely needs more work.
