Where can one find pre-built search engine classes or scripts for PHP, and what considerations should be taken into account when building one from scratch?

To find pre-built search engine classes or scripts for PHP, one can search on popular code repositories such as GitHub or Packagist. When building a search engine from scratch, considerations should be taken into account such as the type of data being searched, the search algorithm to be used, indexing strategies, and performance optimization. 

// Example PHP code snippet for building a basic search engine class

class SearchEngine {
  
  private $data;

  public function __construct($data) {
    $this->data = $data;
  }

  public function search($query) {
    $results = [];
    
    foreach ($this->data as $item) {
      if (stripos($item, $query) !== false) {
        $results[] = $item;
      }
    }
    
    return $results;
  }
}

// Example usage
$data = ['apple', 'banana', 'cherry', 'date'];
$searchEngine = new SearchEngine($data);
$results = $searchEngine->search('an');
print_r($results);
