Site-specific searching from the address bar
In Chromium based web-browsers (Chrome, Brave, etc.) go into your settings and search for site search.
Once you find the settings, click on Add under Site Search. This will give you a form like so:
  
Search engine is the name that will be displayed in the address bar when searching
Shortcut is the string you type in the address bar that will begin the site-specific searching
URL is the desired search url, putting %s where your search terms will go.  
For example, searching through all of the TILs can be done with
https://til.hashrocket.com/?q=%s
Now with this in place, you should be able to something like the following, to quickly view all TILs on a certain topic:
til vim
  
Now you can enjoy easily learning about the thousands of things all the Hashrocketeers have learned for themselves over the years!
