The search box now works on the older releases !
We have deployed the doc of v22.0 and v21.03 ( the 2 versions officially supported) but we will put 21.12 back in the doc site too.
If you urgently need the v21.12 doc it is available here
BTW I have seen the suggestion to use Dgraph instead of Algolia. That’s a good idea for a project :
anyone interested in building a crawler, indexer and metadata management solution based on Dgraph ?
