So IIUC the information re number of deleted documents is only visible
temporarily and only when there are many documents, right?
Thanks

My code at the moment is as follows:

int numberOfDocsBeforeDeleting = reader.numDocs();
log.info("Number of documents: " + numberOfDocsBeforeDel
You have to reopen the index reader to see deletes from the indexwriter.

Did you call this method before or after commit method?
My wild guess would be that you can count deleted documents inside
transaction only.

IIRC, it's the number of documents marked with a "deleted" bit. They are
obliterated during merges as segments written during the merge operation no
longer include deleted contents. So eg. if you call forceMerge(1), no
previous segment is preserved and the deleted count will drop to 0 as a
result.

except that when I delete some documents from the index, then the method
https://lucene.apache.org/core/9_0_0/core/org/apache/lucene/index/IndexReader.html#numDeletedDocs()
always returns 0, whereas I would have expect
