What are some recommended tools or libraries in PHP for creating a search index and improving search functionality?

Creating a search index and improving search functionality in PHP can be achieved by using tools or libraries such as Elasticsearch, Solr, or Algolia. These tools provide powerful search capabilities, including full-text search, relevance ranking, and filtering options, to enhance the search experience for users. 

// Example code using Elasticsearch to create a search index and improve search functionality

require 'vendor/autoload.php'; // Include the Elasticsearch PHP client library

use Elasticsearch\ClientBuilder;

$client = ClientBuilder::create()->build(); // Instantiate a new Elasticsearch client

$params = [
    'index' => 'my_index', // Specify the name of the index
    'body' => [
        'settings' => [
            'number_of_shards' => 1,
            'number_of_replicas' => 0
        ],
        'mappings' => [
            'properties' => [
                'title' => ['type' => 'text'],
                'description' => ['type' => 'text'],
                'price' => ['type' => 'float']
            ]
        ]
    ]
];

$response = $client->indices()->create($params); // Create the index with specified settings and mappings

// Perform search queries using Elasticsearch query DSL to retrieve relevant results
