This is my preferred way of searching almost anywhere. Not just here.
In fact, I have implemented a custom search engine for this exact purpose. I just enter gs <search term> in the omnibar, and Google will search for the given term on the current url.
gs is for "Google Site Search".
Go to chrome://settings/searchEngines and click Add.
Now enter
From now on, wherever you are, just enter gs <term> to seach for that term.
I have used it for years. And I have a bunch of similar search engines.
