Packages

Package Version Description
FastFind.Core NuGet Core interfaces, SIMD string matching, StringPool
FastFind.Windows NuGet NTFS MFT direct access, USN Journal sync
FastFind.Unix NuGet Linux/macOS parallel enumeration, file monitoring
FastFind.SQLite NuGet FTS5 persistent index

Key Features

  • Cross-Platform SIMD: Vector256/Vector128 auto-dispatch (AVX2, SSE2, NEON) — 1.87M ops/sec
  • MFT Direct Access (Windows): 31K+ files/sec NTFS enumeration, 30x faster than standard APIs
  • Parallel BFS Enumeration (Linux/macOS): Channel-based depth-aware parallel traversal
  • Real-Time Monitoring: USN Journal (Windows) / inotify (Linux) / FSEvents (macOS)
  • SQLite FTS5: Persistent full-text search index
  • Memory Optimized: 60-80% reduction via StringPool interning
  • Auto Platform Detection: ModuleInitializer auto-registration

Installation

dotnet add package FastFind.Core

# Platform-specific (auto-registered at runtime)
dotnet add package FastFind.Windows    # Windows
dotnet add package FastFind.Unix       # Linux / macOS

dotnet add package FastFind.SQLite     # Optional: persistent index

Quick Start

using FastFind;

// Platform auto-detected — creates Windows, Linux, or macOS engine
using var engine = FastFinder.CreateSearchEngine();

await engine.StartIndexingAsync(new IndexingOptions
{
    SpecificDirectories = [@"D:\Projects"],         // Windows
    // MountPoints = ["/home", "/opt"],             // Linux / macOS
    ExcludedPaths = ["node_modules", ".git", "bin", "obj"],
    CollectFileSize = true
});

while (engine.IsIndexing) await Task.Delay(500);

var results = await engine.SearchAsync(new SearchQuery
{
    BasePath = @"D:\Projects",
    SearchText = "controller",
    ExtensionFilter = ".cs",
    MaxResults = 100
});

await foreach (var file in results.Files)
{
    Console.WriteLine($"{file.Name} ({file.SizeFormatted}) - {file.DirectoryPath}");
}
