lucene

This is the standard Aussom-Lang Lucene module. This module provides full-text indexing and search capabilities based on Apache Lucene v10.4.0, which is actively maintained and released under the Apache 2.0 license.

It provides two index types: an in-memory index for fast ephemeral indexing within a single session, and a file-system-backed index that persists across sessions. Plain text and Markdown files are supported, with Markdown syntax stripped before indexing.

Usage

Here's a short example, please see the API doc for details.

// Create an in-memory index.
idx = new luceneMemoryIndex();
idx.create();

// Add files to the index.
idx.addTextFile('/path/to/doc.txt');
idx.addMarkdownFile('/path/to/doc.md');

// Commit before searching.
idx.commit();

// Search the index.
results = idx.search('keyword');
foreach (r in results) {
    c.log(r['path'] + ' (score=' + r['score'] + ')');
    c.log('  ' + r['snippet']);
}

// Close the index.
idx.close();
