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.

Hi
I am using Lucen 9.4.2 vector search and everything seems to work fine,
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 expected that it would return the
number of documents which I deleted from the index.
IndexReader.numDocs() returns the correct number though.
I guess I misunderstand the javadoc and in particular the note "*NOTE*:
This operation may run in O(maxDoc)."
Does somebody explain in more detail what this method is doing?
Thanks
Michael
