.NET Standard / .NET 5 / .NET 6 Support

The next generation of Lucene.NET is under development. Lucene.NET 4.8.0 supports the latest .NET platforms, and the Lucene.Net.Contrib library has now been split up into specialized libraries.

Lucene.NET Needs Your Help

Lucene.NET 4.8.0 is a large project that has been under development since 2014, and a few volunteers have contributed more than 5000 hours of their time to help. All of the Lucene.NET modules are ported from Java, but we are still missing a few key features and have much work to do on our biggest dependency, ICU4N, to get it production ready.

If you wish to contribute your time, please see the Contributing page to get started. Specifically, the types of people we need to get Lucene.NET 4.8.0 out of beta are:

  • An engineer with advanced concurrency debugging and design skills
  • Someone with experience fund raising for open source
  • Some developers to experiment with and blog about Lucene.NET and to help us make the user experience better by creating more documentation

We understand some people and companies don't have the time to contribute code or write documentation, but still wish to participate. While Apache provides much of the infrastructure we need through Apache sponsorship programs, these funds generally are not applied toward development work of Lucene.NET.

Being that Lucene.NET has over 450,000 lines of code and depends on several other projects that we also maintain, development on Lucene.NET is no small endeavor. It can be difficult for a small team of developers to put in the kind of time that a project of this magnitude requires, which is why we need your help. Lucene.NET needs more regular developers devoting periodic blocks of development time and it needs sponsorships so some of those developers can allocate substantial amounts of time to the project.

These sponsorships are not officially affiliated with the Apache Software Foundation, but aim to support endeavors related to Apache Lucene.NET. The ASF values community integrity and vendor independence very highly. As a general principle, it doesn't accept "cash for code" so that individual cash payments can't force contributions into a project which aren't aligned with community consensus.


Some of the developments we may be able to accelerate through this initiative include:

  • Performance optimization.
  • Fixing tests that are still failing intermittently.
  • Implement randomized test repeatability in the Lucene.Net.TestFramework project for easier debugging GH-288.
  • Finish ICU4N packaging, and provide a way to make smaller custom distributions of ICU data using the ICU Data Build Tool.
  • Automation of website and API documentation build and deployment.
  • Online API documentation for J2N.
  • Production release of Lucene.NET 4.8.0.
  • Upgrade of Lucene.NET from 4.8.0 to the latest stable version of Lucene (approximately 1800 hours of work).

Funding may also be applied toward:

  • Ongoing support of Lucene.NET 4.8.0 and higher.
  • Development hardware and virtualization of debugging environments.
  • Reporting bugs found in .NET platform and development tools.
  • Documenting policies and procedures for use by the Lucene.NET development team.
