Sometimes you can't remember the place, person, or title of something you know you saw. In that case, try this search method.
For example, you remember participating in a discussion during the last three months about how to increase customer survey participation, but you can't remember the discussion title, which space the discussion occurred in, or the other participants. Use the Spotlight search at the top right and type in keywords such as customer survey. Click View all Results and then click Discussions in the top menu because you don't need to see results from blogs, documents, or polls.
Tip: Still can't find the discussion? Is it possible it wasn't a discussion that you remember? Next you might try looking in the comments of documents or blogs.
