RiSearch PHP Guide for Distributed Search and Index Optimization

Overview of RiSearch PHP Distributed Search and Indexing

With the rapid growth of data, search engines play an increasingly important role in information retrieval. In distributed environments, search and index management become more complex. RiSearch is a powerful PHP search engine library that provides comprehensive solutions to help developers efficiently handle search and indexing in distributed systems.

Key Features of RiSearch

RiSearch supports distributed search and indexing. In a distributed environment, data is stored across multiple nodes, requiring the search engine to quickly locate the relevant data. RiSearch uses the Inverted Index technique to index keywords and quickly find matching documents. Additionally, it distributes indexes across multiple nodes and uses a Coordinator to manage search operations, enhancing search efficiency and handling high concurrency and large datasets.

Installing RiSearch

RiSearch can be installed in a PHP development environment using Composer:

composer require moonsearch/php-async-lib

Index Management in Distributed Environments

Managing indexes across multiple nodes requires coordinated operations. The following code example demonstrates distributed index management with RiSearch:

<?php

require_once 'vendor/autoload.php';

use MoonSearchCoordinator;

$coordinator = new Coordinator('tcp://127.0.0.1:6569');

// Add index shards
$coordinator->addIndex('index1', 'tcp://127.0.0.1:6570');
$coordinator->addIndex('index2', 'tcp://127.0.0.1:6571');
$coordinator->addIndex('index3', 'tcp://127.0.0.1:6572');

// Add documents to the index
$coordinator->indexDocument('index1', 'document1', [
    'title' => 'RiSearch PHP',
    'content' => 'RiSearch is a powerful PHP search engine library.'
]);

// Delete an index
$coordinator->deleteIndex('index2');

// Merge indexes
$coordinator->mergeIndexes(['index1', 'index3'], 'mergedIndex');

// Retrieve index information
$indexInfo = $coordinator->getIndexInfo('mergedIndex');
print_r($indexInfo);

// Execute search
$results = $coordinator->search('mergedIndex', 'RiSearch');
print_r($results);

?>

Distributed Search Operation Example

RiSearch uses a Coordinator to perform distributed search operations. Here is an example:

<?php

require_once 'vendor/autoload.php';

use MoonSearchCoordinator;

$coordinator = new Coordinator('tcp://127.0.0.1:6569');

// Execute search
$results = $coordinator->search('mergedIndex', 'RiSearch');
print_r($results);

?>

In this example, the Coordinator object $coordinator is used to perform the search operation. Developers simply need to specify the Coordinator's address and call the search method. RiSearch will automatically distribute the search task across nodes and merge the results.
