Hi, you may also have a look at the implementation of the PKIndexSplitter, doing exactly what you want (applying a FilterReader / FilterCodecReader that hides documents matched by a query): https://github.com/apache/lucene-solr/blob/master/lucene/misc/src/java/org/apache/lucene/index/PKIndexSplitter.java#L127-L170
