I sometimes use the Dogpile meta to punch up poor searches.
Google searches have turned into a joke.
I used to be able to search my own posts on FR. Fr gets perhaps a page now.
Google has taken to looking at your search terms and deciding what you really want is something else. All I can think of is that I use search terms that, based on my 40 years in the software business, will give results using a simple text comparison, but in fact AI analyses the terms as though I said them to another human and comes up with different criteria. Another possibility is that they dork up the results until you log in. Maybe someone with a google account can speak to that. Anyway, DDG is working well for me and I avoid google whenever I can.
