If nobody notices this, lemme explain. Google search provides a smart option called "search personalization". Google would collect the data of what you have searched last time and try to personalize what you want to see in the later search. Sounds good? NO, check this out.
Summary: Search Personalization makes you see "only what (they think) you want to see", kinda filter that filtrate your vision of the information in the cyber world.
I saw this TED talk many months ago and I just went through it. Later on I found out that Google really did this and it is really annoying. First I use the keyword to search the articles on facebook, however, when I use the old keyword again to search for the same articles, Google's search personalization did their great job by show up the things that "they think I want to see but actually I don't want to see"! Yeah, that article is gone...
If you don't want to lost your previous search result, or don't want to have the Google's filter, this link provides solution to fix it.
