Seems yahoo has added a new feature on their search engine called the search suggest, where their search box will have a drop down list of search term ready to be click if you are searching that particular phrase or word. See picture as an example. If you feel that this feature is annoying you can also disable it at your choice by clicking the disable link at the drop down box shown.

According to Yahoo Blog, this is new to their search engine though it is not new on some search engines now on the net. Some excerpts on their blog

The nice thing about the suggestions is that they’re not obtrusive, so if you already know what you’re searching for, you can overlook the suggestions without them getting in your way. But, when you experience those brain dead moments like we all do, it’s the type of feature that just might get things moving again. If you don’t like change, you can turn it off altogether by simply selecting “disable” in the bottom right corner of the drop down menu. And, if you’re having regrets, you can reinstall it by selecting “more” above the search box.

Nice addition to their search engine that we don’t have to type all the phrases we want to search that can save time of course.
