Search bar no longer working post sandbox refresh

found the solution and surprisingly not documented at  https://support.gainsight.com/Gainsight_NXT/Administration_and_Permissions/General_Administration/Gainsight_Sandbox_Management 😓

I was coming in here to share exactly what you found already @AnaCosta . No, it is not well documented. I suggest an internal doc of post-refresh steps required based on your org setup...and based on hangups of Gainsight. 

A few other notes that you may want to consider post-refresh:

• You need to request for support to turn on email service in order to be able to send any emails from sandbox, including report/dashboard link share emails
• For those link share emails, you need an SSL config setup between support and your IT team as well, otherwise the links will appear as unsafe and possibly unclickable
• If you are looking to test end to end JO emails, you should also get the CNAME setup to whitelist the Sendgrid email domain
• If you are using External Actions in any rules, they all need to be reset up, including the Connectors set up and access key info
• S3 bucket needs to be reset up, including any config of rules or Data Designs using this

Hope this is helpful!
