Just now I was searching on godoc.org. Its result page (eg https://godoc.org/?q=ical) suggests "Try this search on Go-Search or GitHub". "Go-Search" is a link to https://go-search.org, whose TLS cert expired on February 23, and is serving 503 service unavailable responses.
Perhaps remove the link to Go-Search.org from the search results page?

I created an issue https://github.com/daviddengcn/gcse/issues/41 about the TLS cert and errors, I believe that's the right repo, but am not sure.
