copy-segments

Name

index-copy-segments - Copies segments from one index to another index.

Synopsis

lucene index copy-segments <INPUT_DIRECTORY> <OUTPUT_DIRECTORY> <SEGMENT>[ <SEGMENT_2>...] [?|-h|--help]

Description

This tool does file-level copying of segments files. This means it's unable to split apart a single segment into multiple segments. For example if your index is a single segment, this tool won't help. Also, it does basic file-level copying (using simple FileStream) so it will not work with non FSDirectory Directory implementations.

Arguments

INPUT_DIRECTORY

The directory of the index to copy.

OUTPUT_DIRECTORY

The directory of the destination index.

SEGMENT, SEGMENT_2

The segments to copy, separated by a space.

Options

?|-h|--help

Prints out a short help for the command.

Example

Copy the _71_Lucene41_0 segment from the index located at X:\lucene-index to the index located at X:\output:

lucene index copy-segments X:\lucene-index X:\output _71_Lucene41_0
