+## Examples
+
+Simple
+
+```bash
+sink {

+        hosts = ["localhost:9200"]
+        index = "seatunnel-${age}"
+    }
+}

+
+CDC(Change data capture) event
+
+```bash
+sink {
+    Easysearch {
+        hosts = ["localhost:9200"]
+        index = "seatunnel-${age}"
+        
+        # cdc required options
+        primary_keys = ["key1", "key2", ...]
+    }
+}
+```
+
+SSL (Disable certificates validation)
+
+```hocon
+sink {
+    Easysearch {
+        hosts = ["https://localhost:9200"]
+        username = "admin"
+        password = "admin"
+        
+        tls_verify_certificate = false
+    }
+}
+```
+
+SSL (Disable hostname validation)
+
+```hocon
+sink {
+    Easysearch {
+        hosts = ["https://localhost:9200"]
+        username = "admin"
+        password = "admin"
+

+        username = "admin"
+        password = "admin"
+        
+        tls_keystore_path = "${your Easysearch home}/config/certs/http.p12"
+        tls_keystore_password = "${your password}"
+    }
+}
+```
