This is because a typical SolrCloud install spreads the index across multiple servers. Each server has no idea what the other servers are doing as far as indexing. So rollback is disabled in cloud mode. In standalone mode where each index core is a separate entity with no connection to any others, you can do a rollback ... but it will NOT be the document you just added/deleted/changed, it will be *EVERY* change since the last searcher was opened. Solr does not support transactions like a database does. https://lucene.apache.org/solr/guide/7_4/uploading-data-with-index-handlers.html#rollback-operations Thanks, Shawn
Re: Does solr support rollback or any method to do the same job？
Surprisingly, you can delete recently added doc not yet committed doc, Lucene tracks the sequence and after following commit there will be no that document. "To rollback" delete/update one need to send original doc. But literally there'is no fine grained rollback operation.
