I search for "cta form 5 coupler".
It doesn't find the page I was looking for, and most of the results are irrelevant to the Chicago Transit Authority Form 5 coupler that I was searching for.
The strangest result that I want to call out is the 10th top-level (most out-dented) result: it is "Google", simply to https://www.google.com. Results are attached.
I expected to find this page as one of the first results:
https://www.chicago-l.org/FAQ.html
Reasons: it's very deeply into Chicago Transit Authority (CTA) and mentions "CTA" 137 times. It also mentions "Form 5 coupler" twice.
