Lucene.NET is a source code, class-per-class, API-per-API, algorithmic port of the Java Lucene search engine to the C# and .NET platform utilizing the Microsoft .NET Framework and .NET Standard. NOTE: You should almost always include the [lucene] tag when using this one. The Lucene.NET design is similar to its Java counterpart and you are more likely to get a satisfactory answer when it is included.
