Yeah I've noticed this a lot in recent months/years. Have been finding myself putting most of the keywords of the query in quotation marks to get any kind of results relevant to my actual query. Like 'printer "scaling" "draftsight"' just so that G wouldn't make some stupid assumptions.
One page of results with 8 of 10 completely unrelated.
It interprets what it thinks I meant instead of listening to the actual words that came out of my mouth.
I have the same problem with my wife... :-)
Language is used to convey meaning. The difference between my wife and Google is that Google tries to interpret language in the lowest common denominator which leaves all people who try to use language properly feeling like they need to learn a new one just to be understood by their search engine.
...maybe that's not so different.
What finally pushed me away from Google was its incorrect assumption of equivalence between different terms. I'd search something like "printer scaling draftsight" and it would return results with "printer" "scaling" and "autocad" all in bold. Because autocad and draftsight are 2D CAD programs, and autocad is more popular, so suuurely that's what I wanted.
