Working with unique values

[Zetta420]

Do you want to request a feature, an issue, or report a bug?
A feature I guess.
What is the current behaviour?

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

What is the expected behaviour?
A way to filters the result by unique value. For examples, I got multiple documents with a "name" value. If I got multiple documents with same name, filtering them to get only one.
I know I can use distinct, but distinct is filtering, but returning only the fields you requested.

If this is a feature request, what is the motivation or use case for changing
the behaviour?
I actually need for filtering my +35 000 movies db where there is some duplicates, and I need to keep them in db, but I need for search to avoid duplicates. Thank you !
Please mention other relevant information such as Node.js and mongoose version.
