Advanced Search not searching Code using Gold trial

We’re giving a try to the Gold trial, specifically because we want to try functionality such as Advanced Search to search through code

We’ve started the trial, however when we use the global search it doesn’t seem to search through the code as shown in the documentation.

Is there something additional that needs to be activated of some sorts or are we missing something (taking into account that we’re using, not self-hosted)?
