Code looks fine to me - one thing missing are some short docs. Docs should probably be split into:

• user section explaining what search is and maybe short screenshot.
• admin section explaining how to configure (e.g. what fields need to be set where)

@khalilcodes this now has conflicts so i can't merge.

[khalilcodes]

Yes will merge along with added docs.

The build seems to be failing here for some reason (suspecting package-lock after merge). Here's some more info on why the build can fail - https://nextjs.org/docs/messages/failed-loading-swc

I will close this and create a new branch with PR as the commits have become messy here.
