If you want to delete data from the Solr Index then you just need to simply run a single query in browser.


http://<hostname>:<port>/<solr-app-name>/<core-name>update?stream.body=<delete><query>*:*</query></delete>&commit=true


Let us see an example:

Suppose, I have a core with name "Solr_sample" and my solr server is running on port 8983, then the query will be:


http://localhost:8983/solr/Solr_sample/update?stream.body=<delete><query>*:*</query></delete>&commit=true
