About

Fuzor is a dependency-free full-text search library for PHP. It tokenises your documents, stores an inverted index in a single SQLite file, and scores results with Okapi BM25 — no external services required.

• BM25 ranked search with automatic typo tolerance
• Boolean search with AND / OR / NOT operators
• Faceted filtering and per-value counts
• Search-as-you-type prefix matching and phrase search
• Stopword filtering and Snowball stemming for 62 languages
• Result highlighting and snippet extraction
• One SQLite file per index — zero infrastructure

Installation

composer require onstage2426/fuzor

Requirements: PHP 8.5+, SQLite 3.46.0+

Usage

use Fuzor\Index;
use Fuzor\SchemaConfig;
use Fuzor\SearchOptions;
use Fuzor\FacetRange;

// Create an index — declare facetable fields at creation time
$index = new Index('/path/to/products.db', schema: new SchemaConfig(
    language:    'en',
    facetFields: ['type', 'price'],
));

$index->insert([
    ['id' => 1, 'title' => 'Fast sedan',     'body' => 'City car with great fuel economy.',    'type' => 'sedan', 'price' => 24900],
    ['id' => 2, 'title' => 'Off-road SUV',   'body' => 'Built for adventure and any terrain.', 'type' => 'suv',   'price' => 41500],
    ['id' => 3, 'title' => 'Electric coupe', 'body' => 'Zero emissions and instant torque.',   'type' => 'coupe', 'price' => 58000],
]);

// BM25 ranked search — typo tolerance fires automatically on words ≥ 5 chars
$result = $index->search('economi');

// Boolean search
$result = $index->searchBoolean('sedan or coupe -electric');

// Faceted search — filter by attribute, count values
$result = $index->search('car', new SearchOptions(
    filter: ['type' => ['sedan', 'suv'], 'price' => FacetRange::max(45000)],
    facets: ['type'],
));

$result->hits;               // documents in relevance order
$result->facetDistribution;  // ['type' => ['sedan' => 1, 'suv' => 1]]
