Faceting with solr php client - php

Question

I am trying to get the faceting results and I don't know how. there are no documentation for solr-php-client. In this example, print_r( $response->getRawResponse() ) does not include faceting. I am not sure weather faceting is not successfully requested or it is a matter of accessing the faceting data in the responce. Please also help me if there is any documentation available online for solr-php-client.
An other question is how to declare "user/password" if solr is protected when initiating the instance of solr-php-client
require_once( 'solr-php-client/Apache/Solr/Service.php' );
$solr = new Apache_Solr_Service( 'localhost', '8983', '/solr/products' );
if ( ! $solr->ping() ) {
echo 'Solr service not responding.';
exit;
}
$offset = 0;
$limit = 10;
$queries = array(
'name:iphone'
);
$additionalParameters = array(
'facet' => 'true',
'facet.field' => array(
'category'
)
);
foreach ( $queries as $query ) {
$response = $solr->search( $query, $offset, $limit );
if ( $response->getHttpStatus() == 200 ) {
print_r( $response->getRawResponse() );
if ( $response->response->numFound > 0 ) {
echo "$query <br />";
foreach ( $response->response->docs as $doc ) {
echo "$doc->id $doc->name <br />";
}
echo '<br />';
}else{
echo "zero results";
}
}
else {
echo $response->getHttpStatusMessage();
}
}

Answer 1

I missed to add $additionalParameters to the search arguements;
$response = $solr->search( $query, $offset, $limit,$additionalParameters );
