How can a beginner structure a database to efficiently store and retrieve search results in PHP?

When structuring a database to efficiently store and retrieve search results in PHP, it is important to use proper indexing on the columns that will be frequently searched. Additionally, utilizing full-text search capabilities or implementing a search engine like Elasticsearch can greatly improve search performance. Lastly, consider denormalizing data or using caching mechanisms to further optimize search queries. 

// Example of creating an index on a column in MySQL
CREATE INDEX idx_search_column ON table_name (search_column);

// Example of performing a full-text search query in MySQL
SELECT * FROM table_name WHERE MATCH(search_column) AGAINST('search_term' IN BOOLEAN MODE);

// Example of using Elasticsearch for search functionality in PHP
// Install Elasticsearch PHP client via Composer: composer require elasticsearch/elasticsearch
$client = Elasticsearch\ClientBuilder::create()->build();
$params = [
    'index' => 'your_index',
    'body' => [
        'query' => [
            'match' => [
                'search_column' => 'search_term'
            ]
        ]
    ]
];
$response = $client->search($params);
