The string "@cuda" probably appears hundreds of times in this particular repo, ex here.
I try to search using the search box like this:
MWE #1 (searching repo code for string "@cuda"):
https://github.com/JuliaGPU/CUDA.jl/search?q=%40cuda&unscoped_q=%40cuda
Message:
We could not perform this search Search text is required when searching source code. Searches that use qualifiers only are not allowed. Were you searching for something else?
MWE #2 (searching repo code for string "\@cuda") Maybe the "@" needs to be escaped?
https://github.com/JuliaGPU/CUDA.jl/search?q=%5C%40cuda&unscoped_q=%5C%40cuda
