The system disabled indexers because their caps are incomplete, it says:
The config of this indexer is incomplete. Please click the button at the bottom to check its capabilities and complete its configuration.
So I would expect the "Recheck cap for incomplete indexers" option to work on these indexers, but instead I have to manually run the check one by one. It's time consuming.
Version is 7.2.3 on Linux if it matters.
Thanks!
