Hover over the Dashboard button in the Toolbar and click Posts.

Enter your Search item next to Title.
Without having to press anything, the first 100 search results will automatically appear.
When the CMS searches for your entry, the search looks for the string of characters you type in, not the WORD. For instance, if you typed in "book", two possible search results include "John Steinbeck on finishing a book" as well as "The History and Sociology of Facebook".
