### Add suggest documents from source of index

```java
DocumentReader reader = new ESSourceReader(
    client,
    suggester.settings(),
    "contentIndexName",
    "contentTypeName");
suggester.indexer().indexFromDocument(reader, 2, 100).getResponse();
```

### Add suggest document from queryLog

```java
QueryLog queryLog = new QueryLog("field1:value1", null);
suggester.indexer().indexFromQueryLog(queryLog);

Elasticsearchにインデックスされているコンテンツを解析してサジェストドキュメントを生成します。

```java
DocumentReader reader = new ESSourceReader(
    client,
    suggester.settings(),
    "contentIndexName",
    "contentTypeName");
suggester.indexer().indexFromDocument(reader, 2, 100).getResponse();
```

### Add suggest document from queryLog

クエリーログ（query_string）を解析してサジェストドキュメントを登録

```java
QueryLog queryLog = new QueryLog("field1:value1", null);

        final int docPerReq = fessConfig.getSuggestUpdateDocPerRequestAsInteger();
        final SystemHelper systemHelper = ComponentUtil.getSystemHelper();
        suggester.indexer().indexFromDocument(() -> {
            final ESSourceReader reader = new ESSourceReader(ComponentUtil.getSearchEngineClient(), suggester.settings(),
                    fessConfig.getIndexDocumentSearchIndex());
