Blog crawler search engine

Create a simple search engine that operates by crawling blogs and public profiles like Myspace, Facebook, Bebo, etc, to extract results for the user. The search engine will work by crawling the world's newly posted blog and profile entries for occurrences of phrases and words matching the search criteria or the searcher. It should also have all the standard functionalists of a standard search engine like Advanced Search, Image Search, Customizable Preferences and Language Settings (English or Any Language). Through it's customizable preferences, users can store certain information about themselves that will be used by the search engine every time they visit the site to filter their search results further. There will also be a database functionality.
