typesense

I have an index.php file where I instantiate the DB class and use the methods. Do I need to add anything else here? I think I'm doing the search correctly ...

`&lt;?php`
`require 'vendor/autoload.php';`
`require './SearchDB/DB.php';`


`use Dotenv\Dotenv;`
`use SearchDB\DB;`


`$dotenv = Dotenv::createImmutable(__DIR__, '.env.development');`
`$dotenv-&gt;load();`

`$db = new DB();`

`$db-&gt;getProductQueries();`

`if (isset($_GET['q'])) {`
  `$searchResults = $db-&gt;search($_GET['q']);`
  `$products = $searchResults['products'];`
  `$facets = $searchResults['facets'];`
`}`

`?&gt;`

`<!DOCTYPE html>`
`&lt;html lang="en"&gt;`

`&lt;head&gt;`
  `&lt;meta charset="UTF-8"&gt;`
  `&lt;meta name="viewport" content="width=device-width, initial-scale=1.0"&gt;`
  `&lt;title&gt;Search Results&lt;/title&gt;`
`&lt;/head&gt;`

`&lt;body&gt;`
  `&lt;form action="" method="GET"&gt;`
    `&lt;input type="text" name="q" placeholder="Search for products" value="&lt;?= isset($_GET['q']) ? $_GET['q'] : '' ?&gt;"&gt;`
    `&lt;button type="submit"&gt;Search&lt;/button&gt;`
  `&lt;/form&gt;`
  `&lt;ul&gt;`
    `&lt;?php if (!empty($products)) : ?&gt;`
      `&lt;?php foreach ($products as $product) : ?&gt;`
        `&lt;li&gt;&lt;?= $product['document']['id'] ?&gt; - &lt;?= $product['document']['manufacturer_id'] ?&gt;&lt;/li&gt;`
      `&lt;?php endforeach; ?&gt;`
    `&lt;?php else : ?&gt;`
      `&lt;li&gt;No results found&lt;/li&gt;`
    `&lt;?php endif; ?&gt;`
  `&lt;/ul&gt;`
`&lt;/body&gt;`

`&lt;/html&gt;`
