It's even bad for finding something to purchase honestly. I'll search for a specific part number, and most of the results are other similar but not interchangeable products. No Google I cannot just shove this random other battery pack into my UPS, but thanks anyway.
I tried searching for airtight drawers and all the results were either airtight or drawers. Only one was both and it was a ten thousand dollar museum specimen cabinet.
It's especially terrible if you care about the fiber content of your clothes. Searching for linen or even 100% linen gets me linen blend, linen-look, linen color. 100% wool gets mostly acrylic wool blends. Wool toe socks gets me either wool socks or toe socks but again, not both.
Plus I can't block Amazon and Walmart from the results anymore, so that's a ton of extra junk to filter through manually.
You would think so wouldn't you? But Google usually still tries to be "helpful" about everything. "100 linen" does work better, although still not perfect.
That also doesn't fix the issue with being unable to ignore Amazon and Walmart. On the standard search, the dash to ban a specific term makes it not the first result but it still shows up further down the page. On the dedicated product search it doesn't seem to do anything at all.
Here's an example of how well search operators do these days.
I just signed up for the free trial of Kagi, I'll have to see how it compares.
