Develop approximate search functionality using PHP and Manticore Search

Using PHP and Manticore Search to develop approximate search functions

Introduction:
In the modern information society, how to efficiently retrieve and search large amounts of data is an extremely important issue. In practical applications, users often encounter incorrect input or input errors, which requires the use of approximate search functions to improve the accuracy of search results. This article will introduce how to use PHP and Manticore Search to develop approximate search functions.

Manticore Search Introduction:
Manticore Search is an open source full-text search engine developed based on Sphinx Search. Compared with traditional database queries, Manticore Search provides a more efficient full-text indexing function and can support full-text search of large data sets.

Install Manticore Search:
Before starting development, we need to install Manticore Search first. Manticore Search can be installed through the following command:

sudo apt-get update
sudo apt-get install manticore

After the installation is complete, the Manticore Search service can be started using the following command:

sudo systemctl start manticore

PHP code example:
Next, we will use PHP to write A simple example to demonstrate how to leverage Manticore Search for approximate search.

First, we need to introduce the Manticore Search PHP library, which can be installed through Composer:

composer require solarium/solarium

Then, we need to create a Search class to search for Manticore Search:

<?php

require_once 'vendor/autoload.php';

use SolariumClient;

class Search {
    private $client;
    
    public function __construct() {
        $config = array(
            'endpoint' => array(
                'localhost' => array(
                    'host' => 'localhost',
                    'port' => 8983,
                    'path' => '/',
                )
            )
        );
        
        $this->client = new Client($config);
    }
    
    public function search($query) {
        $select = $this->client->createSelect();
        $select->setQuery($query);
        $result = $this->client->select($select);
        
        return $result;
    }
}

Next, we can call the Search class in the main file to search:

<?php

require_once 'Search.php';

$search = new Search();
$query = 'apple';
$result = $search->search($query);

foreach ($result as $document) {
    echo $document->id . ': ' . $document->title . '<br>';
}

This example will search for articles containing the keyword "apple" in the title and print out the title of the article.

Approximate search function:
In addition to precise search, Manticore Search also supports approximate search function. We can use the tilde symbol (~) in the query statement to indicate approximate search. For example, if you change the query to "apple~", Manticore Search will return results that contain "apple" or are similar to "apple" in the title.

$query = 'apple~';
$result = $search->search($query);

Summary:
This article introduces how to use PHP and Manticore Search to develop approximate search functions. Manticore Search provides efficient full-text indexing capabilities and can support full-text search of large data sets. By using Manticore Search's approximate search function, we can more accurately obtain the search results that users need.
