Today I had forgotten the word "outliers" but I knew it is in statistics, and also it refers to unusual data points.
So I did a search https://duckduckgo.com/?q=statistics+unusual+points
But I could not find the word "outlier" in the first page, whereas this:https://duckduckgo.com/?q=statistics+unusual+points+!g
Shows what I was looking for in the first page.
I have no idea how to better explain my problem, but sometimes it is good if a search engine understands the hidden meaning. Is that the larger corpus that gives Google a better *understanding* or maybe a HMM, but in any case I think this is the main reason we still have to have !g every once in a while
