## 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.

        relatedQueryService.getRelatedQuery(id).ifPresent(entity -> {
            copyBeanToBean(entity, form, copyOp -> {
                copyOp.excludeNull();
                copyOp.exclude(Constants.QUERIES);
            });
            form.queries =
                    stream(entity.getQueries()).get(stream -> stream.filter(StringUtil::isNotBlank).collect(Collectors.joining("\n")));
        }).orElse(() -> {

        final EditBody body = new EditBody();
        copyBeanToBean(entity, body, copyOp -> {
            copyOp.excludeNull();
            copyOp.exclude(Constants.QUERIES);
        });
        body.queries = stream(entity.getQueries()).get(stream -> stream.filter(StringUtil::isNotBlank).collect(Collectors.joining("\n")));
        return body;
    }
