Ok, it took me even more time to stabilize the build than I initially expected as there were 4 misbehaving issues (4388, 4397, 4398, 4399)
The PR that reverts SEARCH is https://github.com/apache/calcite/pull/2250 I'll let the dust settle, and I merge it. Hopefully, SEARCH then could be re-added when it is ready. Vladimir
