Thinking back to around 1995-2005, I really regret how so many "search" tools (both online and in certain OSes) have become opaque and unreliable "let me guess it for you" engines. Features to correct them when they are wrong--like negation of terms--are sometimes unreliably badly/non-documents, or nonexistent.
It's not a lack of knowledge or skill--FFS Youtube owner Google has its own history as a search engine there--but all the commercial incentives aligned for Enshittificiation, and I wish I knew how to fix it.
