If you set fuzzy to true, words with a Levenshtein distance <= 3 will be taken into account. This is a lot slower though (Apple M1, Node v19.1):

test	performance
non-fuzzy – berlin charlottenburg	704 ops/sec
fuzzy – berlin charlottenbrug (note the typo)	204 ops/sec

Setting completion to false speeds things up:

test	performance
completion – Münc Hbf	477 ops/sec
no completion – Münc Hbf	2115 ops/sec
