OP was saying that the search quality of sites vary and used the commonly cited example that Reddit’s search bar with “<search query>” is not as good as doing a Google search with “<search query> site:reddit.com”

You are describing the fact you don’t like to look at Reddit which is a bit different as OP was just using Reddit as an example for a general concept of using google instead of a site’s internal search functionality.

Incidentally you can solve your issue by typing “<search query> -site:reddit.com” to remove any results coming from Reddit instead of having to scroll past results you don’t want to see.
