If your profile is still mired in the old Twitter interface, you can still search, of course, but getting things started takes a lot more work. Here are the steps to follow.
1. In any Twitter page, scroll to the bottom of the page.
2. Click the Search link. The Twitter Search page appears.
3. Type a search term in the text box.
4. Click the Search button. You can also press Enter or Return. Twitter displays the tweets your search term found either in the text or the tweeter’s username. Figure 6.7 shows an example results page.
