## 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
);

/**
 * {@link Iterator} with index. The index starts from {@literal 0}.
 *
 * <p>
 * Usage example:
 * </p>
 *
 * <pre>
 * import static org.codelibs.core.collection.IndexedIterator.*;
 *
 * List&lt;String&gt; list = ...;
 * for (Indexed&lt;String&gt; indexed : indexed(list)) {
 *     System.out.println(indexed.getIndex());
 *     System.out.println(indexed.getElement());
 * }
