Oh funny, thanks for that. I was experimenting with keyword recommendation the other day, and I told a friend that the keywords which appear in 19% of the results for a query seem like the most useful and relevant to the original query.
He said something like, “Oh, 80% comes from 20%.” I didn’t get it, but he must have been referencing this.
It's not limited to the context of search engines, the 80/20 phenomenon is well documented in many places: https://en.wikipedia.org/wiki/Pareto_principle
