curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$search = [];
$search['query']['bool']['must'][]['match']['name'] = 'laptop';
$search['aggs']['brands']['terms']['field'] = 'brand';
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($search));
$resp = curl_exec($curl);
$data = json_decode($resp, true);
curl_close($curl);
foreach ($data['aggregations']['brands']['buckets'] as $bucket) {
echo $bucket['key'] . ' (' . $bucket['doc_count'] . ')
';
}
