In the jQuery folder, there are unused files like LICENSE.txt, PACKAGE.json, AUTHOR.txt and others. It seems you are using two js files so you must remove the rest as we need to keep file size into consideration. Kindly make appropriate changes. :+1:

For a particular typed search term, the suggestions must be limited to 5 results. You may choose the 5 results randomly from the suggestion set. Additionally, you might want to make the UI smoother and the suggestions should not displace the page content and should appear over them.
Kindly take a look into this and make appropriate changes :+1:
