Full-text search in JavaScript

First we need to make available a searchable JSON document.

It can probably be normalised to relatively plain text before being converted into a search index.

The search index is a structure that incorporates language specific search features like stemming, phonetic similarity and other helpful things.

After reading a bit about solutions like elsasticlunr, lunr, fuse and flexsearch, it seems like the latter, flexsearch is the fastest current alternative (2021-07).


It allows us to add all our documents to the index, then export the index into a static file that could be loaded client side.

I imagine building the index during the build step and serving it as a highly cached static file that can be loaded on the client.

My goal is to have a fast and good search for my knowledge base in the client.

The website used as a navigation environment for the knowledge base is per now (2021-07) a static htnl website. No client side react or similar.
