Issue:
You’re trying to find some text in a local repo on Github. You’re confused because the big search bar at the top left seems to want to search across the entire Github, not just this repo.
Solution:
In the big search box type:
repo:spatie/dashboard.spatie.be text-invers
repo refers to the repo search specific command
spatie/dashboard.spatie.be is the actual name of the repo
text-invers is the text you are looking for
