This is like allowing many users to access the disk your database is on. Don't do it.
If by "many users on a server", you mean many users having shell access, well, you have many more problems than securing the Solr index. If you mean you have many users accessing an app that lives on the server, the normal process is that the app lives on another server, the Solr server is behind a firewall that the app server can get throught, and the app keeps malicious commands from being sent. If your users have unlimited ability to send URLs at Solr, don't let them know they can fire http://solr_server:8983/solr/collection/update?commit=true&<delete><query>*:*</query></delete> Perhaps you should back up a ways and descirbe your environment, this really smells like an XY problem.
