Not the parent, but a recent example of a failed search for me was:
"Saerang story lord of the rings"
The most important term got dropped and needed to be quoted to actually find what I wanted.
A separate and more concerning problem with Search is the emphasis on shallow information without outgoing links for more depth. The majority of searches on many topics (medical topics for example) will have the top results be "terminal" webpages that offer only a very shallow look at a topic without any way of finding more detailed information.
For example, when I attempted to look for a comprehensive breakdown of biodegredation of plastics (e.g. what kinds of environments reduce/increase biodegrading time, what types of plastics have longer times and why) I just kept finding pages by various advocacy groups that talked in vague generalities and offered no opportunities for further research.
Often, I have to rephrase my search 5-10 times before I see a result worth clicking on.
