### Resumo { #summary }

Eu costumava dizer que não gostava tanto de história... e olha eu aqui agora dando aulas de "história tech". 😅

```java
import org.codelibs.fess.suggest.request.popularwords.PopularWordsResponse;

PopularWordsResponse popularWords = suggester.popularWords()
    .setSize(20)                    // top 20 words
    .setQuery("tech*")              // filter pattern
    .execute()
    .getResponse();

popularWords.getItems().forEach(item -> {
    System.out.println("Popular: " + item.getText() + 

In this guide, you'll learn how to generate a **TypeScript SDK** for your FastAPI backend.
