to show Additional Word in Suggestion

(from github.com/biligee)
How to show 追加ワード in キーワードサジェスト? I have tried to add 全文検索 with yomi both in katagana and hiragana like ぜんぶんけんさく and ゼンブンケンサク. When I start typing ぜん, 全文検索 is not showing in suggestion.

I also tried /search/suggest?query=ぜん

It seems I need to run Suggest Indexer job.

Yes, you need to do that.
