Nessus exploitable vulnerabilities

Here, am trying to find all vulnerabilities found during a nessus scan that are exploitable. The exploit_available field is shown only in nessus plugin. I would like to corelate the exploitable vulnerabilities with hosts in my network which are only shown in the nessus scan sourcetype. My search query works but once again, it takes a while to run. Any help fine tuning this is welcome. sourcetype="nessus:scan" plugin_id="*" [search sourcetype="nessus:plugin" exploit_available="true" id="*" | table plugin_name] | dedup plugin_id |table plugin_name, plugin_id, severity Thanks
