Please, can you let me know how can I delete documents using post utility?

Answer 1

I have done workaround for it using curl. But if anybody have better solution please suggest.

Answer 2

You could try by creating a bash script. Put the document ids inside an array. Then loop the document ids using the following bin/post command:

bin/post -c "collection name" -d '<delete><id>"document id"</id></delete>'

Ex: bin/post -c gettingstarted -d '<delete><id>42</id></delete>'

(from https://lucene.apache.org/solr/guide/7_4/post-tool.html )

One word of advice, as I had issues with the post tool yesterday: restart your Zookeeper and then your Solr ensembles before you proceed using the post tool.

All the best!
