There's a UI design element here which I don't like. The UI presents a text field which is for entering search terms. You click it and expect to type - but NO! - SURPRISE!!! it's actually a button!! And now the page changes, pops up an actual text field, somewhere else and new, and you abruptly are forced to set aside your thoughts about search to process the page layout a second time and go and click again to type in a term. Why on God's clean Earth would anyone ever do this?
