Unfortunately, you can't easily recover from this (except by reindexing your docs again).
Failing to call IW.commit() or IW.close() means no segments file was written... It is theoretically possible to reconstruct a segments file by "listing" all files and figuring out which segments there are, deriving the right metadata for them, etc., but I don't think anyone has actually built this yet.
