According to official site the current Recoll version is 1.23.2. New version builds fine and seems fully works (I just rename current ebuild).
Created attachment 486020 [details, diff] Diff between recoll-1.22.4 and recoll-1.23.2 Thanks for the notification. I can confirm it is working well on amd64. I am attaching the diff between the current and new ebuild (only change is to ~keywords).
