Getting 404 for empty input

Describe the bug It looks like it is expected behaviour but I don't think we should allow an empty input call from the frontend.

To Reproduce Don't type anything in the search box and press enter. It takes you to https://bundlephobia.com/package which gives 404.

Expected behavior I believe we should just do nothing when the input is empty.

Let me know if the suggested fix is good and I can make a relevant PR for the same.
