I'm pretty sure the reason the dub registry search is inaccurate 
is due to the limitation of MongoDB's built-in Text search. The 
$text operator only due well for the EXACT match [1] so partials 
might not work. I personally don't rely on it for search 
functionality. You have to give it the exact word you're looking 
for in MOST cases.

Their Cloud offering however comes with a special search product 
[2][3] (elasticsearch under the hood... if I remember correctly) 
for accurate search.

Another alternative is to roll out a self-hosted elasticsearch 
instance for text search.

MeiliSearch [4], built-in rust, is simple and clean for my taste. 
It's what I'm going to use for my little side-project.
