Results accuracy

[RiccardoManzan]

Do you want to request a feature, an issue, or report a bug?
issue

What is the current behaviour?
I cant find a way to improve results accuracy.
I'm using this package to get users that have email similar to a particular one.
I would like to find something like "[email protected]" and "[email protected] as match of "[email protected]", but right now i got matches really different from my search email.
I can even find null values in results.
I tried to change minsize and weight values unsuccessfully

If the current behaviour is a bug, please provide the steps to reproduce.

What is the expected behaviour?

If this is a feature request, what is the motivation or use case for changing
the behaviour?

Please mention other relevant information such as Node.js and mongoose version.
Using mongo 3.6, node 10.23 and version 2.0.2 of this package.
