I'm not very (I mean, at all) conversant with Javascript. So stuff like Gulp, Grunt, etc is outside my comfort zone. But one fine day, someone posts step-by-step tutorial[1] on how to set up static site search using Fuse.js on Hugo sites without Gulp, Grunt, etc., and I am finally able to set up search[2] on my Hugo generated blog in no time.
