I just ran a Google search for "Correctional Institute" and it got 285,000 hits. I often do this to see how frequently a certain word or phrase is used. But from the wording of the query, I'm not sure if that's what you're asking about.

FWIW, if you want to find out how often similar phrases are used, (although I don't set much store in it) you could try this:https://www.googlefight.co.uk/

This is what I do all the time as well, but I am confused when hundreds of thousands of hits suddenly drop to mere hundreds when you get to, say, page 21 or 22. Why is this happening?
