Is deleting with IndexReader still possible?

Hi

According to the FAQ one can delete documents using the IndexReader

https://cwiki.apache.org/confluence/display/lucene/lucenefaq#LuceneFAQ-HowdoIdeletedocumentsfromtheindex?

but when I look at the javadoc of Lucene version 8_8_2

https://lucene.apache.org/core/8_8_2/core/org/apache/lucene/index/IndexWriter.html
https://lucene.apache.org/core/8_8_2/core/org/apache/lucene/index/IndexReader.html

then it seems to me, that deleting documents is only possible with
IndexWriter, but not anymore with IndexReader, right?

Thanks

Michael

Good catch Michael, removing from IndexReader has actually been removed a
long time ago. I just edited the FAQ to correct this.
