Package Version Description
FastFind.Core NuGet Core interfaces and models
FastFind.Windows NuGet Windows-optimized with MFT & USN Journal
FastFind.SQLite NuGet SQLite persistence with FTS5 search

Key Features

  • SIMD-Accelerated Search: 1.87M ops/sec with AVX2 hardware acceleration
  • MFT Direct Access: 31K+ files/sec NTFS enumeration (30x faster than standard APIs)
  • USN Journal Sync: Real-time file change detection
  • SQLite FTS5: Persistent index with full-text search
  • Memory Optimized: 60-80% reduction through string interning
  • Optional File Size: Opt-in file size collection with ~10-30% overhead

Installation

dotnet add package FastFind.Core
dotnet add package FastFind.Windows    # Windows implementation
dotnet add package FastFind.SQLite     # Optional: SQLite persistence

Quick Start

using FastFind;
using Microsoft.Extensions.Logging;

// Create search engine
using var loggerFactory = LoggerFactory.Create(b => b.AddConsole());
var searchEngine = FastFinder.CreateWindowsSearchEngine(loggerFactory);

// Build index first (required before searching)
await searchEngine.StartIndexingAsync(new IndexingOptions
{
    DriveLetters = ['C', 'D'],
    ExcludedPaths = ["node_modules", "bin", "obj", ".git"],
    CollectFileSize = true  // Enable file size collection (default: false for max speed)
});

// Wait for indexing
while (searchEngine.IsIndexing)
{
    await Task.Delay(500);
}

// Search
var results = await searchEngine.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})");
}
