index-fix - Fixes an index by removing problematic segments.
lucene index fix [<INDEX_DIRECTORY>] [-v|--verbose] [-c|--cross-check-term-vectors] [-dir|--directory-type] [--dry-run] [?|-h|--help]
Basic tool to write a new segments file that removes reference to problematic segments. As this tool checks every byte in the index, on a large index it can take quite a long time to run.
WARNING: This command should only be used on an emergency basis as it will cause documents (perhaps many) to be permanently removed from the index. Always make a backup copy of your index before running this! Do not run this tool on an index that is actively being written to. You have been warned!
INDEX_DIRECTORY
The directory of the index. If omitted, it defaults to the current working directory.
?|-h|--help
Prints out a short help for the command.
-v|--verbose
Enables verbose output.
-c|--cross-check-term-vectors
Cross check term vectors.
-dir|--directory-type <DIRECTORY_TYPE>
The FSDirectory implementation to use. If omitted, it defaults to the optimal FSDirectory for your OS platform.
--dry-run
Doesn't change the index, but reports any actions that would be taken if this option were not supplied.
Check what a fix operation would do if run on the index located at X:\product-index\, using verbose output:
lucene index fix X:\product-index --verbose --dry-run
Fix the index located at X:\product-index and cross check term vectors:
lucene index fix X:\product-index -c
