: Subject: How do I send multiple user version parameter value for a delet by id : request with multiple IDs ?
If you're talking about Solr's normal optimistic concurrency version constraints then you just pass '_version_' with each delete block... https://lucene.apache.org/solr/guide/8_4/uploading-data-with-index-handlers.html#sending-json-update-commands {"delete":[{"id":"51", "_version_":123445}, {"id":"5", "_version_":67890}]} ...but it shounds like maybe you're talking about using the DocBasedVersionConstraintsProcessorFactory ? ... in which case I don't think what you're asking about is possible ... I'm pretty sure it's deletion logic assumes you'll send only one delete at a time. As a workaround, you can send the "tombstone" documents yourself (instead of relying on DocBasedVersionConstraintsProcessorFactory to intercept the deleteById commands and convert then into tombstones for you.) -Hoss http://www.lucidworks.com/
