Weight inconsistencies in channel search results

Summary

The channels search is exhibiting mixed behavior in the search results it returns.

Steps to reproduce

Take two channels , /xander and /ottman And note two name types. Username (as in URL) and Name (as on profile).

1. Search xander, don't click anything, just let the dropdown appear and scroll through.
2. Note none of the results are our own @xander-miller

This implies to me that Username is not being taken into account, the only way he appears is if I search his Name (with space), Xander Miller.

1. Search ottman
2. He is top.

This is seemingly taking into account the username. - also works with name.

Platform information

Cross-platform web. Likely affects mobile also.

What is the current bug behavior?

Users cannot find the users they want to find all the time because of this issue.

What is the expected correct behavior?

Hard to say, but ideally, if it is not already, the popularity of the channel should be weighted in as a factor. I think equal weight should be placed on a username and a direct name match also.
