Ten years ago I complained on a random forum about Google's seeming refusal to give me information about running Skyrim under Linux with the Wine emulator. I tried various search combinations and all I could easily get was information about wine manufacturers and locations in the Skyrim world. Didn't matter if I used "emulation" or "wine emulator" or similar terms, even in quotes, or if I used the '+' character, or otherwise tried to harness Google's literal search functions.
Was I searching wrong? Didn't seem so to me at the time, but I don't remember the exact queries. Those in the forum thread thought I just didn't know how to use a search engine. I still think it was Google telling me what it thought I really wanted, instead of what I was literally asking for.
I still see results that don't include words that I search for in quotes, often.
