quarkus-lucene's Introduction

Lucene extension for Quarkus

Apache Lucene is a Java library providing powerful indexing and search features, as well as spellchecking, hit highlighting and advanced analysis/tokenization capabilities.

This extension adds support for building native executables when using Apache Lucene.

Usage

Configuration

After configuring the Quarkus BOM:

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>io.quarkus</groupId>
            <artifactId>quarkus-bom</artifactId>
            <version>${insert.quarkus.version.here}</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

You can configure the lucene extension by adding the following dependency:

<dependency>
    <groupId>io.quarkiverse.lucene</groupId>
    <artifactId>quarkus-lucene</artifactId>
    <version>${insert.release.version}</version>
</dependency>

Limitations

The extension disables the workaround for bug JDK-4724038 in the MMapDirectory. This means that files from the index will not be deleted immediately when Lucene issues a deletion operation, but only upon garbage collection, causing a temporary larger disk usage.
Test Coverage is currently limited to lucene-core ,lucene-analyzers-common and lucene-queryparser artifacts from Lucene.

quarkus-lucene's Issues

Is this repo still maintained?

I want to decide whether to use this or not

Unable to build native image after upgrading from 0.3 to 2.1.0

Error: Could not find target method: private static java.lang.Object org.apache.lucene.store.MMapDirectoryReplacementJDK.unmapHackImpl()

The release version is buggy

Even if the version file is set

name: Quarkiverse Extension
release:
  current-version: 2.0
  next-version: 2.1-SNAPSHOT

the version released is just "2" :)

https://central.sonatype.com/artifact/io.quarkiverse.lucene/quarkus-lucene/2

Add all tokenattribute types

In this PR I've added a couple of attribute types that covered support for some use cases.

Is there a reason why not all attributes from package org.apache.lucene.analysis.tokenattributes are added? Maybe we can just add them all?

Questions because of a lack of documentation

Hello everyone,

I'm not sure if this is the right place for my questions so please correct me if there is a better place to aks them.

As the site https://quarkus.io/extensions/io.quarkiverse.lucene/quarkus-lucene suggests, there is an extension for Quarkus to make Lucene useable. Unfortunately, the documentation link just redirected me to this repository where besides the read me is no information on how to use the extension. I would be very glad if you could show me where to find, if it's existing, guides to use this extension.

And now i'll state my question here anyways for the case that the documentation doesn't exist at all.

My Situation:
I'm trying to use Hibernate Search with a Lucene backend, for now in regular JVM-mode. Therefore i picked this Lucene dependency as well as the regular Hibernate Search ORM dependency (https://mvnrepository.com/artifact/org.hibernate/hibernate-search-orm). On Application start i get the exception which you can find on the bottom of this post. So is this problem because of the Extension which I'm trying to use (maybe because of Quarkus Maven plugin bootstrap sequence generation which doesn't work at this external library) or am I just using the wrong Extension or need to do Configurations or..?

As I said I'm sorry to bother you here but since I can't find any documentation this is my last resort :)

Thank you!
