LuceneServer.NET

LuceneServer.NET is a REST server on top of Apache Lucene.NET. It hosts any number of search indices and makes them available through simple GET/POST requests.

• Written in C# on .NET 10
• Full-text search with Lucene query syntax
• Phonetic search (Soundex, Cologne phonetics)
• Geo filters (bounding box, distance, distance to line) and GeoJSON output
• Grouping (DISTINCT-like) of field values
• Optional Basic authentication with roles (read, write, admin)
• .NET client library LuceneServerNET.Client
• Command line tools to fill an index from existing databases

Motivation

The goal is a quick and easy search. Performance should be high enough to search in real time from autocomplete input fields, even in large amounts of data.

Typical use cases:

• Search in product lists
• Search in large geo data sets such as addresses, plots, etc.
• Indexing documents

The search index is meant for fast lookups. A hit can then be linked to the actual data. It is not a replacement for a database, it only provides a performant and usable search. The included tools fill an index from existing (relational) databases, e.g. periodically; database keys stored in the index link back to the original records.
