 ## 为什么使用 OpenSearch?
 
-OpenSearch is well-suited to the following use cases:
+OpenSearch 是一个高效维护的套件，通常被用于下面的一些情况：
 
-* Log analytics
-* Real-time application monitoring
-* Clickstream analytics
-* Search backend
+* 日志分析（Log analytics）
+* 实时应用监控（Real-time application monitoring）
+* 点击流分析（Clickstream analytics）
+* 后台查询（Search backend）
