README

FTS5 lexical documentation search driver for Marko — fast, dependency-free full-text search over Marko docs.

Overview

marko/docs-fts implements DocsSearchInterface using SQLite's built-in FTS5 engine. It indexes the canonical documentation from marko/docs-markdown into a local SQLite database and answers queries with ranked keyword results. No external services, no model downloads — just SQLite. Use this driver when you want fast, lightweight search without semantic ranking.

Installation

composer require marko/docs-fts

Usage

Build the search index (run once, re-run after updating marko/docs-markdown):

marko docs-fts:build

The index is written to .marko/docs-fts.sqlite. Once built, search is available automatically through the DocsSearchInterface binding and via marko/mcp's search_docs tool.

use Marko\Docs\Contract\DocsSearchInterface;

$results = $container->get(DocsSearchInterface::class)->search('rate limiting');

API Reference

• FtsSearch::search(string $query, int $limit = 20) — BM25-ranked keyword search
