Hello, I'm facing an issue that some shards of my SolrCloud collection is corrupted due to they don't have segments_N file but I think the whole segments are still available. Can I create a segment_N file from the available files?
This is the stack trace: org.apache.solr.core.SolrCoreInitializationException: SolrCore 'my_collection_shard12_replica_n22' is not available due to init failure: Error opening new searcher at
