Google says "tempered spring" in bold. Doesn't sound like the answer you're looking for, but it was very clear.
The majority of the search results are for places to buy a spring clamp. This is because the overwhelming majority of people who search for that term are looking to buy them, not to learn about what they are. I assume this is true for most specialized parts and equipment.
The majority of humans are more interested in accomplishing a task than they are in any form of learning. So that's what Google optimizes for. They have billions of users and most of them aren't looking to learn about how anything works on a given day. They just need to buy a clamp, or whatever.
