Fuse is terrible performance-wise. There are many better options

I tried Fuse, lunr and MiniSearch, and I stayed with MiniSearch. Great flexibility and very good performance even when I am indexing almost a million documents + many useful features.

Also, I would also recommend giving FlexSearch a try, it has some fancy algorithm that supposedly makes searches extra fast https://github.com/nextapps-de/flexsearch?tab=readme-ov-file...

yes, Fuse is extremely slow (and FlexSearch is very fast after indexing is done), but i have no idea how that table presents FlexSearch as having the lowest memory footprint, maybe in its default config?

in my testing of fuzzy/substring matching it takes quite a while to create its huge index: https://github.com/leeoniya/uFuzzy?tab=readme-ov-file#perfor...
