libstdcxx5 does not show up in search results

I tried putting in libstdcxx5 and it did not find anything. Currently on master libstdcxx5 does not even build, so was trying to use your site to use an older version.

Hmm, interesting. The name in the nix file is libstdc++5. Searching for that I do find the result (link).
In the source recipe the name libstdcxx5 is not present anywhere.

The nix packages search shows the real name in the results. I have to look into what causes this discrepancy.
