As a user, I would like an option to output confident candidates only

Is your feature request related to a problem? Please describe.
Not a proble, rather an enhancement.

Describe the solution you'd like
Instead of having to think myself about which candidates make sense or not, have a restricted list with possibly "high confidence" candidates only.

Describe alternatives you've considered
Letting things as they are.

Additional context
Do not forget to document how the choice is performed.

Done for now, filters could be improved later on
