Can you add a search function in your hugo theme

[wangjiaxuan666]

I like your theme , and I change some files for display R code, beacuse mostly I wirte R code bolg.
but with the blogs pages number increase, it's diffcult for people to find the post paper that they are looks for.

So, I really want a search function in my bolg, Unfortunately, I don't know hugo and js, CSS, etc., so I just want to ask you as the author. Can you add search function?
