sdk API and other parts of docs.couchbase.com not being indexed, broken things for indexing

I was looking for a page to point someone to as the latest, and I'm noticing that recent content that is linked from developer.couchbase.com seems to not be indexed by Google.

Looking a bit deeper through webmaster tools, there appear to be a few problems:

• robots.txt just redirects to the documentation-archive
• sitemap.xml just redirects to the documentation-archive

I resolved some issues in the Google search console, but it would be good to check for indexing.

The search I was using was https://www.google.com/search?q=config_+cache+site%3Adocs.couchbase.com%2Fsdk-api%2Fcouchbase-c-client-2.8.3%2F&oq=config_+cache+site%3Adocs.couchbase.com%2Fsdk-api%2Fcouchbase-c-client-2.8.3%2F&aqs=chrome..69i57.4534j0j4&sourceid=chrome&ie=UTF-8

The string config_cache definitely appears there, as does the string cbc, but another example of something that isn't working at the moment is: https://www.google.com/search?ei=xqYxWo_cO8KqjQOii6yYAQ&q=cbc+site%3Adocs.couchbase.com%2Fsdk-api%2Fcouchbase-c-client-2.8.3%2F&oq=cbc+site%3Adocs.couchbase.com%2Fsdk-api%2Fcouchbase-c-client-2.8.3%2F&gs_l=psy-ab.3...5134.5359.0.5611.3.3.0.0.0.0.158.158.0j1.1.0....0...1.1.64.psy-ab..2.0.0....0.cMGMza8EcnE
