# Codebeispiele für die Verwendung von OpenSearch Diensten AWS SDKs
<a name="opensearch_code_examples"></a>

Die folgenden Codebeispiele zeigen Ihnen, wie Sie Amazon OpenSearch Service mit einem AWS Software Development Kit (SDK) verwenden.

Bei *Grundlagen* handelt es sich um Codebeispiele, die Ihnen zeigen, wie Sie die wesentlichen Vorgänge innerhalb eines Services ausführen.

*Aktionen* sind Codeauszüge aus größeren Programmen und müssen im Kontext ausgeführt werden. Während Aktionen Ihnen zeigen, wie Sie einzelne Service-Funktionen aufrufen, können Sie Aktionen im Kontext der zugehörigen Szenarien anzeigen.

+ Erstellen Sie eine OpenSearch Dienstdomäne.
+ Stellt detaillierte Informationen zu einer bestimmten OpenSearch Dienstdomäne bereit.
+ Listet alle OpenSearch Dienstdomänen auf, die dem Konto gehören.
+ Wartet, bis der Änderungsstatus der OpenSearch Dienstdomäne den Status „Abgeschlossen“ erreicht hat.
