The next link explains what it means and how fuzzy search works. The best thing about this link is that it has a link to create your own engine -maybe you can use that
hmm, more complex than i expected. i'm not sure that the in-game's fuzzy search (under Interface on Settings) does that, it's more that usr will match user which currently it won't, but i haven't tested it enough to replicate it myself. much more interested if i can make translatable search work first! ty for the link tho
