For example, I can find gxx_linux-64 on anaconda cloud, but when I search for it using conda search:
conda search -c conda-forge gxx_linux-64
It tells me
Loading channels: done
No match found for: gxx_linux-64. Search: *gxx_linux-64*
PackagesNotFoundError: The following packages are not available from current channels:
