Description

The attribute registry is huge, and it can be difficult to know which namespace to look in. Some form of search underneath the root page across all namespaces would be supremely useful!

Thanks for the feedback, @xeger! The semantic convention documentation is pulled in from the semconv repository, but I don't know that that rules out a search functionality on the website. I'll let our platform expert chime in. @chalin?

The site has search, but it is site-wide. We don't have in-page search at the moment.

Can you give examples of the types of terms that you'd search for?
