i would also recommend that if you want to try a new search for something you haven't tried searching for, clear your browser history. google, by the use of cookies, builds a database of searches you've done, and the results you've clicked on, and builds a browsing profile on you. if you spend most of your time googling cat videos on youtube, and want to look for electronic projects, your first page (or first few pages) of results will be cat videos, not electronic projects
