Are there any existing PHP applications or libraries that can be helpful in creating a custom search engine?

To create a custom search engine in PHP, you can utilize existing libraries such as Elasticsearch, Solr, or Sphinx. These libraries provide powerful search functionalities and can be integrated into your PHP application to handle indexing, searching, and ranking of content efficiently. 

// Example code using Elasticsearch PHP library to create a custom search engine
require 'vendor/autoload.php';

use Elasticsearch\ClientBuilder;

$client = ClientBuilder::create()->build();

$params = [
    'index' => 'my_index',
    'body' => [
        'query' => [
            'match' => [
                'title' => 'search keyword'
            ]
        ]
    ]
];

$response = $client->search($params);

foreach ($response['hits']['hits'] as $hit) {
    echo $hit['_source']['title'] . "\n";
}
