How to add identical keys to search parameters

[IvanHoliak]

Is there such a possibility or can someone tell me how to add several or many identical keys with different values ​​to search parameters?
It might look like this:
/items?tag=tag1&tag=tag2&tag=tag3 ...etc

and do navigation:
navigate({ search: (prev) => ({ ...prev, tag: ['tag1', 'tag2'] }), });

and it is possible to do it with zod?

at the moment it was possible to make the URL string looks ugly, just an array of strings in one key
/items&tag=%5B"win"%2C"triple_kill"%5D
