Not knowing how much Google will change its results when it gets lots of related enquiries in a short time, I was reluctant to be too specific. Someone else has now provided an explicit example[0], and I'll provide another example of similar (although not identical) behaviour. Consider this search: "I'm not a mathematician or a puzzler" That finds this page: https://www.solipsys.co.uk/new/SpeakingAtThe2017MathsJam.html https://www.solipsys.co.uk/new/SpeakingAtThe2017MathsJam.htm... This search fails: "So a germ of an idea is enough" That fails, even though it's taken from the same page. This search succeeds: site:www.solipsys.co.uk "So a germ of an idea is enough" This is the example the triggered the question, but the question itself is about experiences I feel I've been having more often over the past 6 or 12 months, and that's better illustrated by the example given in [0].
