Another use-case here. 
I have a setup like this:
Food > Restaurants in San Francisco > {Chinese, Thai, Indian, ...}
Each of those child cards contains a Markdown list of the restaurants of that type in SF.
Unfortunately, they’re all called ‘Thai’, ‘Indian’, etc. When I move from here to NYC (which I’ll likely do soon), those will all be confusing once I make cards on the path:
Restaurants in NYC > {Chinese, Thai, Indian, ...}
For now, I’ve named all of those cards ‘Chinese SF’, ‘Thai SF’, ‘Indian SF’, …
I would prefer to simply ‘archive’ all of them when I move, removing them from search.
I /wouldn’t/ archive ‘Restaurants in San Francisco’, so if I wanted to find them again, I’d jump to that parent card and look at its children.
There’s a search question here too, which relates to Ranking by recency/context in the Command Prompts
