## 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.ndjson" but no results found.

# SMTP server settings for main: host:port
mail.smtp.server.main.host.and.port = localhost:25

# The prefix of subject to show test environment or not
mail.subject.test.prefix = [Test]

# The common return path of all mail
mail.return.path = root@localhost
