Is there any mechanism in place to strip out any personal identifying information such as emails, phone numbers etc from the search analytics?
As this would breach GDPR from what I understand.
The only real option is around how you log the IP address and this can be controlled with the following setting: userid_to_log - Funnelback Documentation - Version 15.24.0
If things like phone numbers or names are input as search queries they can show up in the analytics.
