" Searching by file type and searching by domains is a great way for students to refine their Google searches. Searching for and within a DOC, a PPT, or XLS file can lead students to resources that they might not otherwise have seen. But increasingly a lot of us are creating our documents, slides, and spreadsheets in Google Drive. Many of us are then publishing those files for anyone in the world to see. Thanks to the Google for Education Google+ page, today I was reminded that you can perform a Google search to look for publicly shared Docs, Slides, and Spreadsheets. The screenshots below illustrate how to do this."
