See how “Visited pages” is in black text in the graphic to the left? Just found it tonight. It performs searches with only pages you have previously visited. Ever read a story about Apple, Twitter or Facebook but forgot how you found it? This feature, or is it a function, should enable you to track down what you are looking for rather quickly.
It looks like you must perform a search on Google to see this. The Advanced Search page doesn’t have what I was looking for. Go to Google and perform a search. Then look for something like “All results” to see the “Visited pages” option if it’s hidden. You might need to be logged in to your Google Account too.
