In my work, I often use Google’s advanced search features. For example, I find the “filetype” command particularly useful. It’s extremely easy to use, just type in what you are looking and add “filetype:xls” in case you’d like to see only Excel files containing your search terms. And this is just a beginning of what you can do with Google. If you want to learn more about Google search, I would recommend the following resources:
