> CheckIndex is great for testing and when tracking down lucene bugs.
> But in cases where users just want to verify their index files are OK, it is very slow and expensive.
> I think we should add a -fast option, that only opens the reader and calls checkIntegrity(). This means all files are the correct files (identifiers match) and have the correct CRC32 checksums.
> For our 10M doc wikipedia index, this is the difference between a 2 second check and a 2 minute check.
