The article mentions "correcting" searches as an instance of this. I find that particularly infuriating on Amazon. I often search for a specific thing, let's say, "CRI 95 LED light bulb", and it'll return thing that it determines are close enough. In this case, a CRI 96 or CRI 98 bulb would be fine, but it determines that because a CRI 80 bulb also has the same word in it, that it's close enough. (For context, the "color rendering index" expresses about how close an LED bulb is to an incandescent, and CRI 80 is just a standard cheapo bulb.) I often end up returning things because I searched for something specific, and Amazon returned a bunch of things that were not that. (And it shows that for similarity search, that the "corrections" do need to have domain-specific awareness.)
