LuceneSearchExample

A refreshed Lucene.Net sample targeting .NET 8.0. The console app demonstrates how to build and query a Lucene index, while the integration tests exercise the flow end-to-end using Testcontainers and PostgreSQL.

Requirements

• .NET 8 SDK (see global.json)
• Docker (required for the Testcontainers-powered integration tests)

Getting Started

# Restore dependencies
dotnet restore

# Run the console sample
DOTNET_ENVIRONMENT=Development dotnet run --project src/LuceneSearchExample.App

The console application writes the temporary Lucene index location to stdout and prints matching users for a sample query.

Testing

The integration tests spin up a PostgreSQL container, pull sample users into the Lucene index, and assert the expected match.

dotnet test

If Docker is not available, either skip the tests or mark the SearchServiceIntegrationTests class with your preferred test trait filter.

Project Layout

• src/LuceneSearchExample.App – Console host that drives the demo workflow.
• src/LuceneSearchExample.Search – Reusable library that wraps Lucene.Net index creation and querying.
• tests/LuceneSearchExample.IntegrationTests – xUnit-based tests using Testcontainers and PostgreSQL for realistic data setup.
