In Google web search, when I search for:
+ortho4xp +image +compression
I receive one relevant site result containing the 3 words, followed by 6 results ridiculously telling me "Missing: +ortho4xp".
I only want to see pages that contain ortho4xp ! That's why I typed +ortho4xp
There is no "Must include ortho4xp" link next to these results to let me force the word (although that would be stupid anyway, I've typed the + prefix). I have also tried quoting e.g. +"ortho4xp" but this has absolutely no effect.
Before you ask, I have posted questions on the wasteland that is https://support.google.com/websearch in the past and received absolutely no useful response.
