FastFileSearch 0.1.0 [ALPHA-2026-05-17] — High-Performance Native File Search for Java

---

🔍 Lightning fast fuzzy and prefix search for millions of indexed files.

FastFileSearch provides real-time search capabilities for the FastJava ecosystem. Built on top of FastFileIndex, it allows for instant prefix, fuzzy, and exact matching across massive file collections with sub-millisecond response times.

// Instant fuzzy searchSearchResult[] results = engine.fuzzy("myapp", 100);
System.out.println("Found " + results.length + " matches!");
}

Installation

Option 1: Maven (Recommended)

Add the JitPack repository and the dependencies to your pom.xml:

<repositories>
<repository>
<id>jitpack.io</id>
<url>https://jitpack.io</url>
</repository>
</repositories>
<dependencies>
<!-- FastFileSearch Library -->
<dependency>
<groupId>com.github.andrestubbe</groupId>
<artifactId>fastfilesearch</artifactId>
<version>0.1.0</version>
</dependency>
<!-- FastCore (Required Native Loader) -->
<dependency>
<groupId>com.github.andrestubbe</groupId>
<artifactId>fastcore</artifactId>
<version>0.1.0</version>
</dependency>
</dependencies>

Option 2: Gradle (via JitPack)

repositories {
maven { url 'https://jitpack.io' }
}
dependencies {
implementation 'com.github.andrestubbe:fastfilesearch:0.1.0'
implementation 'com.github.andrestubbe:fastcore:0.1.0'
}

Option 3: Direct Download (No Build Tool)

Download the latest JARs directly to add them to your classpath:

1. 📦 fastfilesearch-0.1.0.jar (The Core Library)
2. ⚙️ fastcore-0.1.0.jar (The Mandatory Native Loader)

Important

All JARs must be in your classpath for the native JNI calls to function correctly.

Try the Demo

1. Clone this repository.
2. Run run-demo.bat.
3. Experience the "Instant" search-as-you-type interface.
