How does Apache Solr Help with WooCommerce?

With Apache Solr, search functionality on your WooCommerce site will be faster, more accurate, and more customizable. Solr can provide more nuanced search functionality, like fuzzy search and synonyms. It can even highlight search terms in search results, allowing customers to quickly see which products are most relevant.

To implement Apache Solr, you will need a Solr server, which you can set up using a hosting platform like AWS or DigitalOcean. After that, you can use the Solr PHP client library to connect your WooCommerce site to the Solr server.

$client = new Apache_Solr_Service($solrHost, $solrPort, $solrCore);
if(!$client->ping()) {
 echo 'Solr service is not available';

$query = $_GET['search'];
$results = $client->search($query, 0, 10);

foreach ($results->response->docs as $doc) {
