In general, no. Cache entries refer to documents by Lucene ID. When a
new searcher is opening, every single Lucene ID in the index might have
changed. That is why searches are re-executed -- the information in the
existing caches cannot be trusted. There is no way for Solr to
determine when an existing Lucene ID has not changed.
