Google Decides to be more Open
Google recently announced their plans to make the inner workings of their search engine more open to the general public. this was detailed in a blog post made by They outlined some simple details about Pagerank, how the team works, how Google evaluates changes, and how they customize searches that are time sensitive such as breaking news, changes in language, the ability to handle phrases, synonyms, diacritics, spelling mistakes, and so on.
