Updated search examples

[shinyichen]

• Use random search examples
• Removed three links on landing page

Suggested change

	const SearchExamples = React.memo(() => {
	const SearchExamples = () => {

I think we can get rid of React.memo here since there aren't any props to compare it against, it'll just re-render everytime anyway.

I added this because it was updating the examples when I click on one of the examples. But it feels very odd to see the examples change when clicked on one of them.

Let me know if there's better way to handle it.
