+## FAQ
+
+#### Q. Kibana can't connect Elasticsearch.
+
+A. Please check `${KIBANA_HOME}/config/kibana.yml` and set correct Elasticsearch URL.
+
+Example:
+```
+# The Elasticsearch instance to use for all your queries.
+elasticsearch.url: "http://localhost:9201"
+```
+
+#### Q. I imported "fess_log.json" but no results found.
+
+A. Is there any search logs? If it still does not resolve, it may be caused by TimeZone. Please check **Settings** -> **Advanced** -> **dateFormat:tz**.
