Add Type Filter Param

Just like how we currently have `{keyword} {query}`, it would be great to have a way to also filter based on types such Attribute, Class, etc as well.

I am currently using the Raycast extension and I get bothered every time I need search, enable the type filter in Dash and then search there to find the correct results, instead of simply do it in Raycast and jump immediately to the wanted page.
