Thank you for this!
I am also quite frustrated with the current state of full text search in the javascript world. All libs I've tried miss the most basic examples and their community seems to ignore it. Will give yours a try but it already looks much better from the comparison page.
Edit: Nope, your lib doesn't seem to handle substitution well (THE most common type of typo), so yep, we are back to square one ...
I settled on MiniSearch. [0] It is fast & small enough and fairly feature complete.
Afterwards I made a few contributions to improve performance and implement a better scoring algorithm. So I'm probably a bit biased now. Take my recommendation with a grain of salt.
Personally I think that OP's library does not perform searches, fuzzy or otherwise. It's much more similar to 'grep'. Try searching for "mario adventures". It won't actually find the most obvious results, because the order of the keywords in the search string must match the order of the keywords in the indexed text.
