PHP and Manticore Search development: Create intelligent search filtering function

Abstract: This article will introduce how to use PHP and Manticore Search to develop an application with intelligent search filtering function. We will use Manticore Search as the full-text search engine and combine it with PHP to implement the search filtering function. Through this article, you will learn how to set up a Manticore Search environment, create indexes, perform full-text search and filtering, and finally implement a fully functional intelligent search and filtering application.

1. Introduction

With the explosive growth of Internet information, users’ needs for information are becoming more and more precise. Although traditional search engines can provide search results, they have certain deficiencies in meeting the precise needs of users. Therefore, it is crucial to provide a better user experience by building an accurate search filtering function.

2. Install Manticore Search

First, we need to install Manticore Search. Manticore Search is a fast, open source full-text search engine with good scalability and high performance. You can download and install Manticore Search from the Manticore Search official website (https://manticoresearch.com/).

3. Create index

After the installation is complete, we need to create an index to store the data to be searched. The following sample code demonstrates how to use the Manticore Search PHP extension to create an index:

<?php

require 'vendor/autoload.php';

use ManticoresearchClient;
use ManticoresearchIndex;
use ManticoresearchExceptionsRuntimeException;
use ManticoresearchQueryBoolQuery;
use ManticoresearchQueryQuery;

try {
    $client = new Client(['host' => 'localhost', 'port' => 9308]);

    $index = new Index($client);

    $index->create([
        'index' => 'myindex',
        'type' => 'mytype',
        'fields' => [
            'title' => ['type' => 'text'],
            'content' => ['type' => 'text'],
            'category' => ['type' => 'text']
        ]
    ]);

    echo "Index created successfully.";
} catch (RuntimeException $e) {
    echo $e->getMessage();
}

?>

The above code creates an index named "myindex", which contains "title", "content" and "category" Three fields. You can adjust it according to actual needs.

4. Full text search

Next, we will learn how to perform a full text search. The following sample code demonstrates how to use the Manticore Search PHP extension to perform a full-text search:

<?php

require 'vendor/autoload.php';

use ManticoresearchClient;
use ManticoresearchQueryBoolQuery;
use ManticoresearchQueryQuery;

$client = new Client(['host' => 'localhost', 'port' => 9308]);

$boolQuery = new BoolQuery();
$query = new Query($client);

$boolQuery->addShould($query->match('title', 'keyword'));
$boolQuery->addShould($query->match('content', 'keyword'));
$boolQuery->addShould($query->match('category', 'keyword'));

$query->bool($boolQuery);

$result = $query->search('myindex', 'mytype');

print_r($result);

?>

The above code performs a full-text search operation, the search keyword is "keyword", and the search scope includes "title", "content" " and "category" fields. You can modify the search keywords and search scope according to your needs.

5. Search filtering

Finally, we will learn how to do search filtering. The following sample code shows how to use the Manticore Search PHP extension to perform search filtering:

<?php

require 'vendor/autoload.php';

use ManticoresearchClient;
use ManticoresearchQueryBoolQuery;
use ManticoresearchQueryQuery;

$client = new Client(['host' => 'localhost', 'port' => 9308]);

$boolQuery = new BoolQuery();
$query = new Query($client);

$boolQuery->addMust($query->match('title', 'keyword'));
$boolQuery->addFilter($query->term('category', 'news'));

$query->bool($boolQuery);

$result = $query->search('myindex', 'mytype');

print_r($result);

?>

The above code adds a filter condition based on the full-text search, and the filter condition is that the "category" field is equal to "news" . You can adjust the filters to suit your needs.

Summary:

Through the introduction of this article, we have learned how to use PHP and Manticore Search to develop an application with intelligent search filtering function. We learned how to set up the Manticore Search environment, create indexes, perform full-text search and search filtering. I hope this article can be helpful to you, and I also hope that you can further learn the powerful functions of Manticore Search through practical applications.
