Parameter filtering in universal search?

Situation

Fictional Situation to explain the question:

Graph:

year<sub>1</sub>/x
year<sub>2</sub>/x

and

year<sub>1</sub>/y
year<sub>2</sub>/y

Each x and y page has
type:: y/x
or some other property.

Question

I want to use the Universal Search and quickly filter search results for type:: x/y.

I am well aware I can use a query in a Page, but I would still like to know whether and how this is possible.

I would like to add that in my case, I might have 200 x, y, z, …, and putting all of them into a dedicated Page would be annoying and not clean.

Have you tried typing the property name, including the colons, and the value?

Yeah, I know that works, but it isn’t a query… A query is nice because there must be an index specifically for them. But that isn’t dramatic, but I want to search in all notes with type:: x which doesn’t really seem to work that way if I’m not missing anything.
