What are the potential pitfalls of relying solely on MySQL for complex search functionalities in PHP applications?

Relying solely on MySQL for complex search functionalities in PHP applications can lead to performance issues and limitations in terms of search capabilities. To overcome this, one solution is to implement full-text search using a dedicated search engine like Elasticsearch. This allows for faster and more advanced search functionalities such as relevance scoring and fuzzy matching. 

// Example PHP code snippet using Elasticsearch for complex search functionalities

// Connect to Elasticsearch
$client = Elasticsearch\ClientBuilder::create()->build();

// Define search query
$params = [
    'index' => 'my_index',
    'body' => [
        'query' => [
            'match' => [
                'my_field' => 'search_term'
            ]
        ]
    ]
];

// Execute search query
$response = $client->search($params);

// Process search results
foreach ($response['hits']['hits'] as $hit) {
    echo $hit['_source']['my_field'] . "<br>";
}
