delete lucene index in ontotext graphdb

I created an lucene index in ontotext graphdb based on graphdb documentation. However i cannot figure out how to delete the index with sparql.

Sparql to create index 

PREFIX luc: <http://www.ontotext.com/owlim/lucene#>
 INSERT DATA {
 luc:analyzer luc:setParam "com.example.CustomAnalyzerFactory" .
 luc:index luc:setParam "uris".
 luc:moleculeSize luc:setParam "1".
 luc:myIndex luc:createIndex "true".
}

What options does <http://www.ontotext.com/owlim/lucene#> support to delete the index

The only way to delete the index is to physically delete it from the file system. The index is located in $GDB_HOME/data/repositories/<repositoryId>/storage/lucene/<indexId>. After a database restart, all plugin information will disappear.

Please note that the plugin won't take any resources unless you refresh it! Having said this I highly recommend you to check the Lucene Connector, which supports automatic data synchronization with the database updates and deleting indexes:
