Please add a grammar to search archives untagged

[gth7754125]

It seems that we can only search untagged archives on the sub view. How can i do this through the search bar? formmer lanraragi can do this through the untagged button.maybe a key word needs to be added.

The carousel/subview is the designed place for new/untagged searches, so I don't plan on adding a button/keyword that does the same thing for now. (The whole point of that view was to cut down on buttons...)

Previously I'll admit it'd be inconvenient as the subview wouldn't update at the same time as regular searches, but now that we have faster searches through #555 I've just changed that. 😤

In case you still want a dedicated untagged button, I believe some of the third-party clients do that through their use of the API.
