+NoWaitForResponseRequest plugin
+-------------------------------
+
+Long-running requests like suggest.buildAll might exceed timeouts. This plugin "tries" to convert the request in a kind of fire-and-forget and doesn't wait for Solr's response. Most reliable if the [cURL client adapter](client-and-adapters.md#curl-adapter) is used.
+
+```php
+<?php
+
+require_once __DIR__.'/init.php';
+htmlHeader();
+
+// create a client instance
+$client = new Solarium\Client($adapter, $eventDispatcher, $config);
+
+// get a suggester query instance and add setting to build all suggesters
+$suggester = $client->createSuggester();
+$suggester->setBuildAll(true);
+
+// don't wait until all suggesters have been built
+$plugin = $client->getPlugin('nowaitforresponserequest');
+
+// this executes the query without waiting for the response
+$client->suggester($suggester);
+
+// don't forget to remove the plugin again if you do need the response from further requests
