Many 5.0 docs not indexed, documentation other than canonical not being indexed by google

Something is preventing Couchbase documentation from being indexed.  I suspect it has to do with a canonical URL.  One side effect of this, and the reason I marked this as a blocker, is that this prevents the 5.0 documentation from being found and indexed by Google.  

Since our search relies on it, that means our built in search doesn't search our 5.0 beta documentation. 

amarantha [X] and I noticed this the other day when looking for docs we knew existed.  Google wasn't finding them.  I hit it again today and tried a few different searches.  It appears some pages that have a canonical URL that will 404, those are indexed.  Other pages that exist in both /server/current and the other version seemingly are ignored.
