Hi @Nick Riches
We apologize for the inconvenience caused.
it's important to note that the search results in Teams include both active and archived channels. This is because the content and conversations in archived teams are kept in a read-only, searchable format. So, even if a team is archived, its content can still appear in the search results.
As an alternative solution, if you have already searched for the team, you can see the team in "Recent Searches" in the search bar.
Meanwhile, to get this feature(More in line with your search habits) more quickly, you can send a feedback directly to Microsoft Feedback to add it in future updates.
Many features of our current products are designed and upgraded based on customers’ feedback. With requirements like this increase, the problem may well be released in the future.
Thanks for your understanding and support.
