fix

Name

index-fix - Fixes an index by removing problematic segments.

Synopsis

lucene index fix [<INDEX_DIRECTORY>] [-v|--verbose] [-c|--cross-check-term-vectors] [-dir|--directory-type] [--dry-run] [?|-h|--help]

Description

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!

Arguments

INDEX_DIRECTORY

The directory of the index. If omitted, it defaults to the current working directory.

Options

?|-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.

Examples

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
