## Advanced Usage

### Index from Existing Documents

```java
import org.codelibs.fess.suggest.index.contents.document.ESSourceReader;

// Index suggestions from existing Elasticsearch documents
DocumentReader reader = new ESSourceReader(
    client,
    suggester.settings(),
    "content-index",        // source index
    "document"             // document type
);

        assertEquals("http://hoge/index.html", htmlTransformer.normalizeUrl(url));

        url = "http://hoge/a/index.html";
        assertEquals("http://hoge/a/index.html", htmlTransformer.normalizeUrl(url));

        url = "://hoge/index.html";
        assertEquals("://hoge/index.html", htmlTransformer.normalizeUrl(url));

        url = "://hoge//index.html";
        assertEquals("://hoge/index.html", htmlTransformer.normalizeUrl(url));
