One of the worst things to come from this Google+ thing was the removal of the "+" for searching on Google itself. You used to be able to use " +go +lang " and get results that were guaranteed to have those two terms on the page. Now you have to use double quotes and other tricks. sigh
On the plus side, Google at least tells you when it omits words and offers to put them back in now. Not that it does much good. Something about Google the search engine changed and now it's impossible to get good results for anything but the most obvious queries. I tried looking up why every commercial pot pie says to let it sit for 5 minutes.
I looked this up years ago and got blog posts explaining it. All I get now is page after page of recipes for homemade pot pies. You'd think after a while some logic would spin up to say "I bet this isn't what they're looking for! Let's try something else." It used to do that.
