It's not only about searching your own repository, it allows you to search through every single public repository on GitHub. I personally use it a lot to learn more obscure APIs which are badly documented or which I'm just not used to, simply search for the method I'm trying to use and find infinite examples of real world usage, along with the code license right next to it.
It's also great if you drank the GitHub kool-aid as you can do a single search and find related code snippets, issues, pull requests and discussions that could possibly help. I'm personally not to big into the ecosystem, in fact I'm considering moving to Fossil so I can have everything inside the repo, but for those who are it's a great feature.
