lucene-cli 4.8.0-beta00017

Lucene.NET command line interface (CLI) tools

The Lucene.NET command line interface (CLI) is a new cross-platform toolchain with utilities for maintaining Lucene.NET and demos for learning basic Lucene.NET functionality.

Prerequisites

• .NET 6.0 Runtime or Higher (.NET 8.0 recommended)

Installation

Perform a one-time install of the lucene-cli tool using the dotnet tool install command, which will install the specified version:

dotnet tool install lucene-cli -g --version 4.8.0-beta00017

[!NOTE] The version of the CLI you install should match the version of Lucene.NET you use. The version can be specified using the --version option of the dotnet tool install command. For a list of available versions, see the versions tab of the lucene-cli NuGet package or run the dotnet tool list command using the package id lucene-cli.

You may then use the lucene-cli tool to analyze and update Lucene.NET indexes and use its demos.

The CLI is configured to roll-forward to the next available major version of .NET installed on your machine, if only a newer one than .NET 8 is found. You can control this behavior by setting the DOTNET_ROLL_FORWARD environment variable or --roll-forward command-line argument to Disable to prevent rolling forward, or LatestMajor to always use the latest available major version, before running the CLI tool.

CLI Commands

The following commands are installed:

• analysis
• demo
• index
• lock

Command structure

CLI command structure consists of the driver ("lucene"), the command, and possibly command arguments and options. You see this pattern in most CLI operations, such as checking a Lucene.NET index for problematic segments and fixing (removing) them:

lucene index check C:\my-index --verbose
lucene index fix C:\my-index
