Helm chart is fetchable but not searchable

Question

I have helm charts for a project my-project uploaded to a repo myrepo. Using helm v3.5.3, if I run

helm repo update
helm fetch myrepo/my-project --version 0.0.1

It downloads the my-project-0.0.1.tgz file I had pushed to myrepo. But when I run

helm repo update
helm search repo myrepo/my-project

I get no results.

Why is this?
