David Turner be60d50452 Allow searching of snapshot taken while indexing (#55511) ... Today a read-only engine requires a complete history of operations, in the sense that its local checkpoint must equal its maximum sequence number. This is a valid check for read-only engines that were obtained by closing an index since closing an index waits for all in-flight operations to complete. However a snapshot may not have this property if it was taken while indexing was ongoing, but that's ok. This commit weakens the check for a complete history to exclude the case of a searchable snapshot. Relates #50999		2020-04-21 13:21:38 +01:00
