Hi, Have you waited long enough for zebra to re-index your catalogue ? To me, what you are describing is not faulty. Once you reverted an imported batch, it takes time to zebra to remove the records from the indexes. Especially if you work with large files. If you waited long enough and the indexes never got updated, I would say it's faulty, yes. But it you reverted the import and search for records right away, I would say it's just zebra that hasn't been able to reindex everything...

That is exactly the way I have used the feature many times in the past- well, once to correct an incorrectly modified batch a few moments after the data was loaded, when I spotted a second necessary correction I had missed (much to my annoyance), and maybe 2 dozen times to rip out previously loaded (often large) batches of records weeks after they had been loaded, once the data was no longer needed.
The problem isn’t that I don’t understand how to use the feature (indeed I love it) but my recent experience suggests it doesn’t work correctly.
Maybe 2 months ago I loaded 11,300 records for a patron-driven-acquisitions program. They were records for streaming media supplied by Kanopy. We bought 85 of the titles. I was asked to remove the records for the titles we had not purchased. I expected it to be a simple task- press Undo Import, and pull all the records out, and add the 85 records purchased back in (I had been supplied with a file of our purchases).
After the job completed, I searched on Kanopy in both staff side and OPAC and found c.250 results, much to my surprise. (I expected to find zero records.) When I clicked on the MARC 710 I was taken to a list of c.7,200 records via (in effect) the authority record for Kanopy (Firm). I could also navigate to that list on OPAC.
However these tendrils were “faulty”. Clicking on the title (for example) in OPAC, took the user to a server error 404- Page not found. (But if they clicked on the 856 they were taken to the Kanopy platform). In staff-side, clicking on the record resulted in an error “Record not found” (well, something similar). Attempting to export the MARC file by biblionumber resulted in an empty export file. (I have supplied my screenshots and notes directly to Fred King, who was asking what rubbish was left after my Undo).
In short, my Undo had NOT worked properly. The database had to be re-indexed to get rid of the tendrils. I have another “Undo” scheduled (two files, one of 2,000 records, one of 30,000 records). I am tempted to have one more try, before raising this issue in Bugzilla. I suspect the Undo will not work, and that yet again we will have to have a re-index. And that in future we will have to rely on Batch Record Deletion, rather than the delightful Undo feature.

Ray- The undo import feature has saved me more than once as I realize immediately after import that I have incorrectly modified the batch of records. Immediately reverting the batch is useful. The other main use for the undo import feature is in ebooks as Fred King talks about in the other thread. Thanks joy

I have been using the Undo import (sort-of “unstage”) as I found this functionality astoundingly useful. It automated a task, reducing a tedious job to a couple of keystrokes.
However I was dismayed to find that after a recent “Undo” of 13,000 records our database was left over 7,000 “phantom records”- they didn’t exist but the indexing had failed to remove all traces of them
We were advised to use the batch record deletion tool, as the Undo feature wasn’t designed to be used in the way I was using it. “… it is meant to unstage records nearer to the point in time of being added”. (And what’s the point of that?) We had to have our database re-indexed to resolve the problem. Is there any point in the Undo feature if the indexer can’t cope? I hate to think what other dross I had left behind in earlier “Undos”!
